I use LECO PEGASUS® BT 4D to separate, identify and quantify secondary metabolites of various organisms. The advantages of the GC×GC system in separation of multi-component mixtures allow us to separate and identify a huge number of compounds in every samples. The ability to separate and quantify low levels of target analytes in mixtures simultaneously with the major components presented at a high level of concentration and to separate coeluted compounds is a great advantage of two-dimensional GC in comparison with one-dimensional GC. The user-friendly ChromaTOF software and excellent technical support make LECO a reliable partner for researcher. Since we started working on this equipment, our results have become more accurate and comprehensive, and our research has reached a new level.

In our lab, the GC×GC-MS device installed by LECO has been a game-changer for metabolic profiling, especially in our multiomics study exploring the intricacies of obesity in young adults. Its sensitivity has been crucial in identifying and quantifying metabolites, even at low concentrations, essential for uncovering subtle changes in the metabolome. Our experience with PEGASUS® BT 4D device has been exceptionally positive, significantly due to the exceptional support of the service team, ensuring the smooth operation and optimal performance of our instrument.

We started using the LECO PEGASUS® BT GC-TOF mainly for target analysis of aliphatic hydrocarbons on environmental matrices; over time we had the need to develop a method for the qualitative characterization of hop leaves samples for a research project, the ChromaTOF® deconvolution software allowed the identification of several compounds, in particular different terpenes. The Pegasus BT GC-TOF thus proved to be an excellent system, easy to use, with high sensitivity and reproducibility, able to perform both non target and target analysis.

I started working with the PEGASUS GC-HRT+ 4D back in my student years. As a novice researcher, with no experience working with similar devices and no training, it was not easy at first. However, after years of working with this instrument and when compared with other sophisticated equipment in the field of gas chromatography - high-resolution mass spectrometry, I can confidently say that the ChromaTOF is the most user-friendly software of all those available now. Such a variety of functions, as well as very clear, convenient, and fast operation, combined with high-tech equipment, allows to get very decent results.

Over the past 5 years of using the Pegasus GC-HRT+ 4D, we have been able to conduct many various environmental studies, identifying trace amounts of substances in the cleanest Arctic environmental objects. At the same time, such a powerful combination of two-dimensional gas chromatography with time-of-flight mass spectrometry made it possible to analyze complex matrices, namely peat combustion products, herbal and tobacco cigarette smoke, petroleum and much more.

It is worth noting the work of the support service, which helped us very quickly and efficiently. I would like to thank the engineers for their work, who were on call almost 24/7. There are still many projects and tasks ahead that will undoubtedly be solved with the help of the Pegasus GC-HRT+ 4D.

FAQ – Separation Science

Answer:
Gas chromatography separates components in a mixture by utilizing a thin silica tube coated with a stationary phase. The components, carried by a gas (the mobile phase), move at different speeds based on their affinities for the stationary phase. This differential migration leads to the separation of the components, allowing for their individual analysis and identification.

Alternative response:

  • Gas chromatography is a technique for separating a mixture of volatile analytes
  • The analytes are transported by a mobile phase (the carrier gas)
    • Become distributed between the mobile phase and a stationary phase
    • The Stationary Phase is attached to the inside of a very fine column
  • Phases are typically characterised by their polarity
  • A polar analyte will be retained by polar column for longer than a non-polar analyte
    • and vica versa

Answer:
LECO uses Agilent 8890 chromatography. The gas chromatograph includes the following features:

  • Compatibility and perfect integration with the mass spectrometer
  • Automatic regulation of gas flows
  • Agilent supported inlets: Split/Splitless (SSL), Multimode (MMI), Programmable temperature Vaporizer (PTV) etc.
  • Programmable oven, up to 450 °C
  • Chromatograph compatible with Fast-GC
  • The GC is completely controlled by and integrated into LECO’s ChromaTOF software

Answer:
The LECO mass spectrometer is connected to the GC via a heated transfer line. The LECO GC-TOF allows you to have a 'full range' acquisition, without compromise, then a targeted and/or non-targeted data exploitation depending on what you want to do.

It consists of an EI (Electronic Impact) source, a 70 cm flight tube, a reflectron and a detector. Vacuum is provided by an internal turbomolecular pump connected to an external secondary pump.

Pegasus-BT-diagramm

Answer:
The mass range of the Pegasus BT is from 10 to 1500 m/z. All masses are collected all the time, unlike quadrupole instruments that collect a single mass at a time (quadrupole scanning mode is single ion monitoring, SIM, quickly scanning across the mass range).

Answer:
GC×GC-TOFMS can detect discrepancies in the composition of food products, helping to expose fraudulent claims of Halal certification and ensure consumer confidence in authentic Halal products.

Answer:
By examining the chemical composition of inks and pigments, GC×GC-TOFMS provides insights into the materials used in Islamic calligraphy and manuscripts, aiding in their preservation and authentication. An example of similar work can be read in this publication on analysing the paints used by Leonardo Da Vinci.

Answer:
LECO’s GC×GC-TOFMS system utilizes two columns with different separation mechanisms, providing enhanced chromatographic resolution for the analysis of complex mixtures. In one dimension the analytes are separated by polarity, or according to boiling point. An additional dimension separates according to an alternative property, of which there are many. This results in a 3D image – the two dimensions of separation and the abundance of the analytes in the third dimension.

Answer:
LECO's StayClean® ion source originates in the requirement for a fast source to match the speed of the TOFMS. Accomplished by reducing ion to ion interactions, such as with the walls of the source. The source was thus designed without walls – so there is nothing to clean. Massively reduced downtimes, especially for complex matrices and more reproducible results.

Answer:
Yes! With superior separation power and precision, LECO’s GC×GC-TOFMS system can uncover hidden details and confidently identify components, even in the most intricate mixtures:

  • Increases detectability
  • Removes analytes from matrix interference
  • Separates co-elluting peaks
  • Creates cleaner peaks, which match closer with libraries
  • Creates structured chromatograms thus further improving identification confidence

Answer:
The cryogenic Quad Jet modulator consistently delivers reproducible quantitative results not only within the lab but also between labs worldwide. This is achieved because:

  • There are two cold jets. So, eluent from the primary column does not flow into the secondary column by mistake
  • The distance between cold zones is identical in every system worldwide, unlike other systems that require manual adjustment and intervention
  • The modulation is completely computer controlled. This along with the 2 separate cold zones, allows for variable modulation periods in the same analysis, vastly improving separation across the chromatogram
  • In the same way the primary column is temperature controlled in the primary oven, the secondary column is also independently controlled, allowing for total control of the chromatogram along the entire column setup

These four features not only improve separation and control, they are also unique to the LECO QuadJet.

Answer:
By combining comprehensive two-dimensional gas chromatography (GC×GC) with high-speed, high-sensitivity time-of-flight mass spectrometry (TOFMS), LECO's GC×GC-TOFMS can separate and identify the complex mixtures of flavours and fragrances in food samples with detail and precision.

Answer:
Yes! LECO’s GC×GC-TOFMS is an excellent tool for non-intentionally added substances (NIAS) analysis in food safety. It allows for the comprehensive analysis of complex food samples, ensuring the detection and identification of potential contaminants and unwanted substances. For example, LECO’s MOSH/MOAH solution is widely recognised as the most comprehensive and rigorous analyser for mineral oil contamination in food stuffs.

Answer:
LECO’s GC×GC technology utilizes two stages of separation, significantly increasing resolution and analysis power compared to traditional gas chromatography. This allows for the detailed separation and identification of complex mixtures with unparalleled precision.

Answer:
LECO’s TOFMS technology offers excellent sensitivity, speed, and resolution in mass spectrometry. By fragmenting and ionizing analyte molecules and separating the fragments based on their mass-to-charge ratio, LECO's TOFMS enables highly accurate identification and detection of compounds in samples. The system not only records to a computer at high speed, it detects at a rate of 32,000 Hz thus producing a very high level of accuracy.

Answer:
GC×GC-TOFMS enables the analysis of dietary supplements for the presence of non-compliant ingredients, such as animal-derived gelatine, ensuring that the products meet the strict requirements of Halal certification.

Answer:
GC×GC-TOFMS is a valuable tool for monitoring air and soil quality near Islamic sacred sites, identifying pollutants that may pose a risk to their preservation and guiding conservation efforts. As an example, Imperial College London have utilised a LECO Pegasus BT 4D to identify microplastics in the air of London. You can read about it here.

Answer:
LECO’s GC×GC-TOFMS system utilizes Time-of-Flight Mass Spectrometry (TOFMS), which provides high-speed detection of ionized compounds based on their mass-to-charge ratio.

Answer:
LECO provides software for data analysis, enabling compound identification, quantification, and other types of analysis based on the mass spectra obtained from the TOFMS.

Answer:
LECO’s StayClean ion source, a standard feature in every Pegasus BT GC-TOFMS and GC×GC-TOFMS system, flushes neutrals and contaminants continuously. This virtually eliminates the need for routine maintenance, allowing you to spend less time on upkeep and more time on your research.

Answer:
Sample handling is crucial in GC-MS analysis. LECO employs advanced sample handling robots called Autosamplers that can handle samples in three dimensions of space. These robots ensure precise and consistent sample preparation, ranging from simple liquid injections to complex processes like chemical reactions, extractions, and accurate dilutions.

Answer:
The first GC-MS was a GC-TOFMS developed in the 1950s. However, the technique was too powerful for data recording at the time. In the mid-1990s the first GC-TOFMS capable of recording the data for processing was developed by LECO. This breakthrough in fast GC-TOFMS technology allowed researchers and analysts to utilize the capabilities of GC-TOFMS for their analytical needs.

Answer:
By combining two-dimensional separation, robust ionization, and high-speed TOFMS detection, and patented deconvolution algorithms LECO's GC×GC-TOFMS system offers a powerful solution for analysing complex mixtures with enhanced resolution, sensitivity, and separation power.

Answer:
By analysing the chemical composition of materials used in ancient Islamic artifacts, GC×GC-TOFMS assists in determining their authenticity, providing valuable insights into historical and cultural heritage. The chemical composition of such artifacts are extremely complex so utilising multidimensional chromatography techniques with high speed TOFMS, a chemical profile can be created. Furthermore, LECO’s post processing software packages, ChromaTOF Tile and ChromaTOF Sync can identify differences between samples to compare artifacts and identify biomarkers.

Information about extractable and leachable components from packaging and delivery devices for pharmaceutical products is a particular area of growing interest. Analytical testing results on this topic are part of many regulatory submission requirements to the FDA. ...

USP 1663 provides guidance on extractables testing and a variety of analytical approaches can meet compliance. High resolution MS is often considered necessary for identification of unknowns, and sample complexity and low-level detection continue to challenge these analyses. Here, we demonstrate a workflow that uses comprehensive two-dimensional gas chromatography (GC×GC) with HR-TOFMS to help address these challenges.

FAQ – Separation Science

Answer:
Gas chromatography separates components in a mixture by utilizing a thin silica tube coated with a stationary phase. The components, carried by a gas (the mobile phase), move at different speeds based on their affinities for the stationary phase. This differential migration leads to the separation of the components, allowing for their individual analysis and identification.

Alternative response:

  • Gas chromatography is a technique for separating a mixture of volatile analytes
  • The analytes are transported by a mobile phase (the carrier gas)
    • Become distributed between the mobile phase and a stationary phase
    • The Stationary Phase is attached to the inside of a very fine column
  • Phases are typically characterised by their polarity
  • A polar analyte will be retained by polar column for longer than a non-polar analyte
    • and vica versa

Answer:
LECO uses Agilent 8890 chromatography. The gas chromatograph includes the following features:

  • Compatibility and perfect integration with the mass spectrometer
  • Automatic regulation of gas flows
  • Agilent supported inlets: Split/Splitless (SSL), Multimode (MMI), Programmable temperature Vaporizer (PTV) etc.
  • Programmable oven, up to 450 °C
  • Chromatograph compatible with Fast-GC
  • The GC is completely controlled by and integrated into LECO’s ChromaTOF software

Answer:
The LECO mass spectrometer is connected to the GC via a heated transfer line. The LECO GC-TOF allows you to have a 'full range' acquisition, without compromise, then a targeted and/or non-targeted data exploitation depending on what you want to do.

It consists of an EI (Electronic Impact) source, a 70 cm flight tube, a reflectron and a detector. Vacuum is provided by an internal turbomolecular pump connected to an external secondary pump.

Pegasus-BT-diagramm

Answer:
The mass range of the Pegasus BT is from 10 to 1500 m/z. All masses are collected all the time, unlike quadrupole instruments that collect a single mass at a time (quadrupole scanning mode is single ion monitoring, SIM, quickly scanning across the mass range).

Answer:
GC×GC-TOFMS can detect discrepancies in the composition of food products, helping to expose fraudulent claims of Halal certification and ensure consumer confidence in authentic Halal products.

Answer:
By examining the chemical composition of inks and pigments, GC×GC-TOFMS provides insights into the materials used in Islamic calligraphy and manuscripts, aiding in their preservation and authentication. An example of similar work can be read in this publication on analysing the paints used by Leonardo Da Vinci.

Answer:
LECO’s GC×GC-TOFMS system utilizes two columns with different separation mechanisms, providing enhanced chromatographic resolution for the analysis of complex mixtures. In one dimension the analytes are separated by polarity, or according to boiling point. An additional dimension separates according to an alternative property, of which there are many. This results in a 3D image – the two dimensions of separation and the abundance of the analytes in the third dimension.

Answer:
LECO's StayClean® ion source originates in the requirement for a fast source to match the speed of the TOFMS. Accomplished by reducing ion to ion interactions, such as with the walls of the source. The source was thus designed without walls – so there is nothing to clean. Massively reduced downtimes, especially for complex matrices and more reproducible results.

Answer:
Yes! With superior separation power and precision, LECO’s GC×GC-TOFMS system can uncover hidden details and confidently identify components, even in the most intricate mixtures:

  • Increases detectability
  • Removes analytes from matrix interference
  • Separates co-elluting peaks
  • Creates cleaner peaks, which match closer with libraries
  • Creates structured chromatograms thus further improving identification confidence

Answer:
The cryogenic Quad Jet modulator consistently delivers reproducible quantitative results not only within the lab but also between labs worldwide. This is achieved because:

  • There are two cold jets. So, eluent from the primary column does not flow into the secondary column by mistake
  • The distance between cold zones is identical in every system worldwide, unlike other systems that require manual adjustment and intervention
  • The modulation is completely computer controlled. This along with the 2 separate cold zones, allows for variable modulation periods in the same analysis, vastly improving separation across the chromatogram
  • In the same way the primary column is temperature controlled in the primary oven, the secondary column is also independently controlled, allowing for total control of the chromatogram along the entire column setup

These four features not only improve separation and control, they are also unique to the LECO QuadJet.

Answer:
By combining comprehensive two-dimensional gas chromatography (GC×GC) with high-speed, high-sensitivity time-of-flight mass spectrometry (TOFMS), LECO's GC×GC-TOFMS can separate and identify the complex mixtures of flavours and fragrances in food samples with detail and precision.

Answer:
Yes! LECO’s GC×GC-TOFMS is an excellent tool for non-intentionally added substances (NIAS) analysis in food safety. It allows for the comprehensive analysis of complex food samples, ensuring the detection and identification of potential contaminants and unwanted substances. For example, LECO’s MOSH/MOAH solution is widely recognised as the most comprehensive and rigorous analyser for mineral oil contamination in food stuffs.

Answer:
LECO’s GC×GC technology utilizes two stages of separation, significantly increasing resolution and analysis power compared to traditional gas chromatography. This allows for the detailed separation and identification of complex mixtures with unparalleled precision.

Answer:
LECO’s TOFMS technology offers excellent sensitivity, speed, and resolution in mass spectrometry. By fragmenting and ionizing analyte molecules and separating the fragments based on their mass-to-charge ratio, LECO's TOFMS enables highly accurate identification and detection of compounds in samples. The system not only records to a computer at high speed, it detects at a rate of 32,000 Hz thus producing a very high level of accuracy.

Answer:
GC×GC-TOFMS enables the analysis of dietary supplements for the presence of non-compliant ingredients, such as animal-derived gelatine, ensuring that the products meet the strict requirements of Halal certification.

Answer:
GC×GC-TOFMS is a valuable tool for monitoring air and soil quality near Islamic sacred sites, identifying pollutants that may pose a risk to their preservation and guiding conservation efforts. As an example, Imperial College London have utilised a LECO Pegasus BT 4D to identify microplastics in the air of London. You can read about it here.

Answer:
LECO’s GC×GC-TOFMS system utilizes Time-of-Flight Mass Spectrometry (TOFMS), which provides high-speed detection of ionized compounds based on their mass-to-charge ratio.

Answer:
LECO provides software for data analysis, enabling compound identification, quantification, and other types of analysis based on the mass spectra obtained from the TOFMS.

Answer:
LECO’s StayClean ion source, a standard feature in every Pegasus BT GC-TOFMS and GC×GC-TOFMS system, flushes neutrals and contaminants continuously. This virtually eliminates the need for routine maintenance, allowing you to spend less time on upkeep and more time on your research.

Answer:
Sample handling is crucial in GC-MS analysis. LECO employs advanced sample handling robots called Autosamplers that can handle samples in three dimensions of space. These robots ensure precise and consistent sample preparation, ranging from simple liquid injections to complex processes like chemical reactions, extractions, and accurate dilutions.

Answer:
The first GC-MS was a GC-TOFMS developed in the 1950s. However, the technique was too powerful for data recording at the time. In the mid-1990s the first GC-TOFMS capable of recording the data for processing was developed by LECO. This breakthrough in fast GC-TOFMS technology allowed researchers and analysts to utilize the capabilities of GC-TOFMS for their analytical needs.

Answer:
By combining two-dimensional separation, robust ionization, and high-speed TOFMS detection, and patented deconvolution algorithms LECO's GC×GC-TOFMS system offers a powerful solution for analysing complex mixtures with enhanced resolution, sensitivity, and separation power.

Answer:
By analysing the chemical composition of materials used in ancient Islamic artifacts, GC×GC-TOFMS assists in determining their authenticity, providing valuable insights into historical and cultural heritage. The chemical composition of such artifacts are extremely complex so utilising multidimensional chromatography techniques with high speed TOFMS, a chemical profile can be created. Furthermore, LECO’s post processing software packages, ChromaTOF Tile and ChromaTOF Sync can identify differences between samples to compare artifacts and identify biomarkers.

Die Metabolomik stellt Herausforderungen sowohl an die verwendeten Analysemethoden als auch an die zur Interpretation der Ergebnisse erforderliche Datenreduktion. Für die vollständige Charakterisierung des Metaboloms ist eine einzelne Analysetechnik nicht ausreichend. Bisher wurde kein Metabolom vollständig charakterisiert. GC-MS bietet jedoch eine etablierte Methode zur Analyse des primären Metaboloms, während LC die sekundären und tertiären Metaboliten untersucht.

 

 

LECO-Lösungen für die Aromaanalyse

Mit der LECO GC-MS-Technologie ist es einfacher denn je, die Quellen von Fehlaromen zu finden. Quantifizieren und screenen Sie Proben mit einer einzigen Injektion – mit der zweidimensionalen Gaschromatografie-Flugzeit-Massenspektrometrie (GC×GC TOFMS) von LECO.

Charakterisierung natürlicher Düfte; Matrix und Entschlüsselung komplexer ätherischer Öle. Identifizierung von Geschmacksverfälschern und unerwünschten Aromen, um die Qualität und Rentabilität zu verbessern. In unseren Anwendungshinweisen und Webinaren erfahren Sie anhand spezifischer Beispiele, wie die GC- und GC×GC-Technologie von LECO Ihr Labor stärken kann, und Sie erhalten detaillierte Infos zu LECOs Lösungen für die Sensorik-, Aroma- und Duft-Analyse.

Folded Flight Path®: Zehn Jahre hohe Auflösung

Das erste Flugzeit-Massenspektrometer (TOF) wurde 1946 vorgestellt und das Design seitdem immer wieder verbessert.
Dank der unbegrenzten Sichtbarkeit der Massenbereiche in allen Spektren und der schnellen Spektrenerzeugung waren die Vorteile der TOF-Massenspektrometrie sofort klar. Während die Geräte immer besser wurden, erreichte man schließlich physische Grenzen, die das Auflösungsvermögen einschränkten. Es gab mehr zu tun.

THE FAST GC TECHNOLOGY FORUM

All the tricks of the trade won't be enough if your instruments can't handle the speed. LECO's Pegasus® line is designed to take full advantage of the speed of TOFMS analyses without sacrificing the sensitivity you need, and our StayClean® Ion Source means you never have to slow down to clean out your engine.

Aberystwyth University

"We originally expected to purchase a quadrupole instrument so buying a TOF was a little unexpected but definitely worth it as the data is far richer than what a quadrupole would have supplied. In the three years we have had the instrument running metabolomic matrixes the source has never been cleaned and the data is still superb and consistent. We love our Pegasus BT, it does a fab job of running my FAME samples including milk, yogurt, kefir, biltong and bacteria."

CNAP | University of York

"Our metabolomics research has utilised a LECO Pegasus 4D for over 15 years. Total downtime has probably been less than 20 days for the entire 15 years. When we do have a problem or even a question about using the instrument, LECO are very swift to respond, resolve the issue and offer support and assistance usually within a day of contacting them, and quite often on the same day. The source has never been cleaned or replaced, and we still have the same detector from the original installation. Multiple papers have been produced using data produced from our LECO and I can honestly say it’s been a great asset to our team at York University."

University of Southampton

"In 2019 EPSRC funded our vision for a regional Centre of Excellence (CoE) in 2 dimensional gas chromatography and mass spectrometry. This Regional CoE, initially embracing the Universities of Bath, Portsmouth, Southampton, and Swansea, will significantly drive discovery, characterisation and quantification of new modalities, delivering a step change in capability for detection and identification of new species that cannot be separated and determined by 1D GC alone.

LECO’s Pegasus HRT 4D GC×GC-TOFMS and the benchtop BT4D GC×GC-TOFMS, both with extensive automated sample handling capability were delivered in late 2019 and early 2020. Installation of these state-of-the-art instruments was complicated by Covid-19 and lockdown 1.0. With such complex instrumentation, and application areas, effective training was key; here LECO took the initiative and provided both bespoke local and on-demand online training.

The level of service support and close collaborative relationship with LECO (applications team and account manager) has been first rate. Both systems can now be operated remotely, enabling high level users from across the South West region to access the instrumentation and allow many complex questions to be probed. Our work covers a vast array of application, e.g. petrochemical, environmental and metabolomics. The data sets are rich and complex, yet simplified by a user friendly software interface. Compared to 1D-GC, the 4D systems provide an astonishing number of additional analyte identifications, giving us deeper insight and understanding of the samples. Combining LECO’s high resolution mass spectrometry with comprehensive gas chromatography, multiple sample handling options such as SPME, Pyrolysis and TD along with full automation has created a world class laboratory of which we are all very proud."

The start of the years begins with the usual enthusiasm, targets set, goals to achieve and strategy to achieve them. I remember being in Dusseldorf for a managers meeting on March the 3rd. Life was still normal, and the word ’lockdown’ was only ever heard on a Friday when my children were watching Wrestling. We were able to travel, visit restaurants and have a beer without the constraints of the facemasks, social distancing and track and trace apps. Life was normal. Within a month the world changed – lockdowns, stay-at-home, work from home, stay safe.

As the LECO customers adapted to this new way of life due to COVID, so did we. Our sales force worked from home and like never before used this relatively unheard-of platform called Microsoft TEAMS to interact with customers.


“I hear the chimes of ‘TEAMS’
calling me in my sleep now.”

LECO UK Facemasks

Our service team continued to work throughout the pandemic with the new additions to their LECO uniform. LECO face masks and gloves. And of course, let’s not forget the bottles of hand sanitiser. As well as remote selling was used, remote service support came to the forefront. Both sales and service teams adapted to continue the high level of support that has become a custom with LECO.

LECO UK has been able to adapt and continued to support our customers while keeping ourselves and customers safe. Let hope moving into 2021 we can get back to some sort of previous normality. The vaccines are coming and there is a glimmer of light at the end of the tunnel but for the moment we continue with the slogan of Hands – Face – Space.

It has for sure been a challenge even though Sweden have had less restrictions. When crossing borders to Norway, Denmark and Finland our service technicians have sometimes had to take Covid-19 tests before. We have been fortunate, no one in our team have been infected as we know of. We haven’t even been to Iceland since the start of the pandemic. Our service technicians try to go by their own cars to customers, which have meant drives up to 14 hours single way.

On the sales side it has of course been a challenge in other ways. But with ‘Teams’, online demos and Virtual Trade show our sales team have connected with our customers in the best way possible. We only attended one real trade show since the start of the pandemic – LabDays in Copenhagen – but the attendance was of course quite thin…

Since 14th of March of 2020, and the declaration of State of alarm in Spain, Leco Instrumentos started to work in a new different way, adapting to the new scenario of pandemic. All the employees completed a training course regarding the new risk at work and the personal protective equipment for COVID-19:

  • We all learnt about the use of face masks and the way to wash our hands
  • Some employees customised their masks… thanks to their mother’s support!
  • Remote working was the only option in most of cases.
  • Virtual meetings have come to stay.
  • The service team has been active since the first day, working in safe conditions.


Remote Service and Move LECO Spain


So far, everything was normal… But LECO Spain had to face a new challenge – to move to a new office. It was a hard task cleaning the old facilities and open boxes – a lot of boxes. And in times of COVID we had to consider to organise small groups at the office working together. Minimising risks was a priority despite of the fact that we needed to be operative in the new facility in a short time. The collaboration of the Tres Cantos-based employees was essential.

But the result made the effort worthwhile! And the Spanish LECO team is ready for 2021!

German Team Wearing Masks

From the perspective of the German Service Centre, a Corona routine has emerged throughout the past months. Customer demands increased - ever so often our service engineers are only allowed to enter labs after presenting a negative Corona test result. Of course, this requires special logistics in scheduling. In addition, there are different Corona rules the federal states of Germany and abroad, which makes planning much more difficult. But our colleagues adapt, as the pictures show, and as our colleague Manuel Lindemann describes below.

"When the pandemic really took off from March / April 2020, I first noticed a lot of uncertainty among both myself and the customers. There were many questions: What is Corona? What happens if I fall ill? How will this affect my work? Will the customers still let me enter their lab? How will LECO react? Now, almost a year later, there are still some questions left to be answered, but as humans we adapt and get used to the new circumstances – positive and negative.

in the beginning of the pandemic, I remember waiting for hours in 100m-long queues between lorry drivers and other visitors at a company and having to wait for the gatekeeper to let me pass. And there were customers who had their "special" views. From "Corona doesn't exist” to “You don't need the mask here" and "We have an internal lockdown, you can't get in" – it was all there.

After one year many questions remain unanswered, but some questions have already become obsolete. What remained as well, unfortunately, are the waiting times at customers‘ sites. Simply walking in and working on a unit is no longer possible. "Where are you from? Have you had contact with infected people? What does your Corona Warn app say? Do you have any symptoms?” ...And so on. What I've also noticed is that social interaction often gets left behind these days unfortunately – be it a casual conversation or just a gesture that disappears behind the mask. But, hopefully that is to come back soon.

But LECO protect their employees very well and always has an open ear for questions – a solution will be found together. All in all, I think we have organised ourselves very well and will probably make it through the rest of the pandemic."

 

Manuel Lindemann & Thomas Post, LECO Instrumente GmbH Deutschland


After a beginning of year full of prospects and projects, the arrival of Covid-19 took us by surprise. Italy was the first European nation to be massively attacked by the virus, the first cases recorded were in the north of the country, particularly in Lombardy, the region where the headquarters of the LECO branch in Italy are located.

To counter the spread of the virus, the entire country was placed in the "red zone" and operations were greatly reduced to adapt to the new situation.

  • The symposium of world interest on the GC×GC in Riva del Garda, as well as other local events, albeit no less important, have been cancelled
  • We did our meetings online
  • The office staff worked in smart working
  • The technical staff continued to follow their customers both remotely via the telephone and with remote interventions, and in person with the help of masks, gloves, overalls and protective goggles.


The pandemic has led us to cover our faces with masks, but it has not managed to extinguish our enthusiasm and we hope that 2021, together with the vaccine, gives us the opportunity to resume showing our smiles.

 

Rita M. Monfredini, LECO Italy S.R.L.


We’re dealing with the pandemic problem in a similar way, like the rest of the world:

  • Using, masks and gloves
  • Struggling with scheduling sales visits
  • Mostly using ‘Teams’ and mobile phones to contact with each other and with customers…

Der Unterschied zwischen Weihrauch und Myrrhe

Es ist wieder die Zeit, in der überall rund um die Uhr Weihnachtslieder gespielt werden und die Leute sich fragen, was genau Weihrauch und Myrrhe sind und was sie zu guten Geschenken macht. LECO hat diese beiden Öle mit einem Pegasus BT 4D analysiert, um die Unterschiede zu bestimmen.

Weihrauch (Boswellia) und Myrrhe (Commiphora) sind beides Harze, die seit Tausenden von Jahren als Parfum und Rauchwerk verwendet werden. Die aus diesen Harzen extrahierten ätherischen Öle können mittels Gas-Chromatografie analysiert werden, was die Wissenschaftler von LECO auch getan haben.

Durch Erweiterung der Analyse um eine zweite Dimension, unter Verwendung der GC×GC-Analyse des Pegasus BT 4D, können noch mehr Informationen aus den extrahierten Proben gewonnen werden. Die GC×GC-Analyse erzeugt inhärent strukturierte Chromatogramme, bei denen chemisch ähnliche Analyten dazu neigen, als geordnete Bänder durch den GC×GC-Trennraum zu eluieren. Dies bietet einen Kontext zur Identifizierung und ermöglicht eine schnelle visuelle Charakterisierung der Verbindungen.

Die Metabolomik stellt Herausforderungen sowohl an die verwendeten Analysemethoden als auch an die zur Interpretation der Ergebnisse erforderliche Datenreduktion. Für die vollständige Charakterisierung des Metaboloms ist eine einzelne Analysetechnik nicht ausreichend. Bisher wurde kein Metabolom vollständig charakterisiert. GC-MS bietet jedoch eine etablierte Methode zur Analyse des primären Metaboloms, während LC die sekundären und tertiären Metaboliten untersucht.

Der Aufstieg der omik-Disziplinen in den letzten Jahren war ein heißes Thema in unserer Gruppe – auch weil unser eigenes Fachwissen in gewisser Weise exakt zu den Bedürfnissen dieser Arbeitsfelder passte. Die Metabolomik ist eine besondere Herausforderung für Trennverfahren und erfordert die Anwendung verschiedenster High-End-Verfahren, einschließlich LC, GC, MS und NMR. Tatsächlich haben die meisten Analysewerkzeuge für die Metabolomik ihren „festen Platz im Labor“ – schließlich ist Multimodalität der einzige Weg, um derart komplexe Proben zu handhaben.

"I have been using a GC-TOFMS Pegasus BT since Januar 2018 for Metabolomics projects. I have mainly analysed murine tissues extracts, and, I'm very happy about its robustness and high sensitivity."

UMR QualiSud, University of Avignon, France

"I use a LECO mass spectrometer for plant metabolomics ; it is an efficient machine with a very low detection limit and the Chromatof deconvolution algorithm allows to find hundreds of compounds in complex extracts."

Faculty of Forestry and Wood Sciences, Czech University of Life Sciences Prague, Czech Republic

"I have been working with LECO instruments for approx. ten years. I worked with the PEGASUS® 4D, TruTOF, GC-HRT and, for few days in Berlin, with the Pegasus BT and BT 4D – I really enjoyed that. There are several reasons why I like working with the devices and why I would not consider using other GC-MS insturments.

  • LECO instruments are reliable and robust with well working peak find and mass spectral deconvolution algorithms.
  • In principle, LECO instruments are allowing both target and non target analysis which can be performed in one run, with nice sensitivity.
  • Data processing is easy and everything is done in one SW – no need to use complicated combinations of SWs.
  • LECO has an excellent customers support"

Wolfson Atmospheric Chemistry Laboratories, University of York

"Following years of service from the old LECO PEGASUS® 4D TOF GC-MS, we upgraded to a new LECO Pegasus BT4D TOF GC-MS. The decision was made due to the exceptional separating power afforded by thecryogenic modulation and the durability of the LECO StayClean® sourcetechnology which has been carried into the updated system. The combination of the two open up a wide variety of analyses to us whichenable use of this instrument in many aspects of our research."

National Centre for AtmosphericScience (NCAS), University of York

"We send instruments into the harshest of environments and run very demanding samples on them. Bearing this in mind, our decision to upgrade the GC-MS at our remote Cape-Verde site to the new LECO PEGASUS® BT was driven by the promise of the StayClean® source. This minimizes down time and eliminates operations which are difficult to carry out when working with remote systems. The increased sensitivity of theinstrument enables us to take smaller sample volumes which again assists with easing the burden placedon the analytical machine. Finally! the upgrade from quadrupole to time of flight mass spec will enable us to keep historical datasets which can be interrogated for any compounds which prove interesting in the future."

Department of Civil Engineering University of Strathclyde

"In 2013, I became responsible for overseeing the department’s analytical suite which included a LECO PEGASUS® 4D GC×GC TOF MS as our flagshipinstrument. I had no experience in gas chromatography and found even a standard GCMS daunting. Over the past years, I received extensive support from LECO. Especially withsupport from LECO UK the instrument is still running strong a decade after purchase. I anticipate it will go for another decade and then some."

ALS Enviromental, United Kingdom

"I believe this technology and methodology will profoundly change water analysis realising major benefits for both laboratories and their customers."

"We at SGS MOSH/MOAH group are using the GC × GC-TOFMS from LECO to separate the highly complex fractions of MOSH/MOAH contaminates in food. When you want to identify special patterns of contamination species amongst other analytics (e. g carotenoids) you need a high separation power in combination with a fast screening MS. This is provided by the LECO TOF. Actually we have a new project together with LECO and another company to quantify MOSH/MOAH fractions. The complexity of the instrumentation is high, but with the support of the application team from LECO we reach our goals."

Environment Reference Lab, APA – Agência Portuguesa do Ambiente

"Initially we had some fears about whether the option of the time of flight detector would be the best for our laboratory, since we have no other system of this kind installed. However, at the end of 6 months of operation with the GC-TOFMS system, it was widely recognized internally that we made the right choice. An easy-to-operate system with high sensitivity, reproducibility and severalanalysis options for a large universe of analytes, and in the most varied matrices increases the versatility of laboratory operation as well as the possibility of responding to the most demanding customer requests."

"Our virtual metabolomics research center has six GC-MS instruments, and the LECO PEGASUS® 4D is the crown jewel of our science park. The results of GC-MS profiling performed using GC×GC technologies has madea strong impression on users and has seriously improved the quality of ourpublications. The fast-scanning capabilities of the TOF-analyzer effectively augment the dataobtained on the ordinary quadrupole, especially when working with the most complexmatrices which are most often the subject of metabolomics analysis. The reliability of the device is especially deserving of praise. The equipment can withstand a very demanding load with constant, round-the-clock operation."

Università degli Studi del Piemonte Orientale, Italy

"With the Pegasus BT 4D performing untargeted analysis today is very easy, thanks to the high sensitivity of the instrument, we are able to mine and analyze any type of sample! A combination of very good sensitivity, quality to price ratio and high flexibility make the Pegasus BT 4D system perfect for analysis of every sample"

University of Naples, Italy

"Pegasus BT is the perfect choice for identifying well-known metabolites at low concentration level in our sample, and also discovering new compounds. The most surprising advantage of the BT system is the ion source robustness! We usually work with dirty and complex samples, but we have never observed drop of sensitivity during our analyses.This reduces the time and cost of our analyses!"

TURKU Metabolomics Facility, Finland

"We use the LECO Pegasus BT instrument for the quantification of small polar metabolites. We developed a hybrid method where we quantitate 51 metabolites with standard curves and screen for any other small polar metabolites in a wide range of biological samples. This assay has a great dynamic range thanks to the sensitivity of the BT. The StayClean® ion source allows us to run hundreds of samples in a batch and be confident that the ion source will remain clean even with dirty samples such as plasma."

Czech Academy of Science, Tschechische Republik

"Compared to GC equipped with a single column, the Pegasus 4D enabled me to separate unbelievable number of analytes! Tens of thousands of separated peaks in one run was not an exception. But where the separation was not perfect, ChromaTOF software and its deconvolution algorithm did the job. Such excellent ‘separating power’ helped me discover new types of plant PCB metabolites."

Helmholtz Zentrum München (HMGU) Department “Comprehensive Molecular Analytics“, Germany

"This combination of ultrahigh chromatographic separation with high mass resolution might be still unique for a commercial available end user system."

Feuerwerk ist ein fester Bestandteil der Feierlichkeiten zum amerikanischen Unabhängigkeitstag. Es wird geschätzt, dass jedes Jahr 16.000 Feuerwerke in den Vereinigten Staaten gibt und die amerikanischen Verbraucher mehr als 1 Milliarde US-Dollar für Feuerwerkskörper ausgeben, um den Feiertag zu begehen! Abgesehen von einem großen Knall und strahlenden Lichtern, wie wirken sich diese Feuerwerke auf die Umwelt um sie herum aus? Der weltweite Hauptsitz von LECO befindet sich in Saint Joseph, Michigan, einem Küstenort am Lake Michigan, an dem Feuerwerke eine bedeutende Szenerie für die Feier am 4. Juli bilden. Im letzten Sommer hielt unser Anwendungslabor es für ein interessantes Experiment, das Wasser rund um den Abschussbereich der Feuerwerkskörper zu testen, um zu untersuchen, ob es kurzfristige Auswirkungen auf die Umwelt gibt. Der Zustrom von Touristen an die Strände des Lake Michigan während des Feiertags trägt sicher auch Chemikalien aus Körperpflegeprodukten (Sonnenschutzmittel und Insektenschutzmittel) zum Wasser bei. Die Auswertung dieser potenziellen Kontaminationen rund um den Feiertag war das Ziel dieser Studie.

Die Analyse wurde durchgeführt, indem Wasserproben von drei verschiedenen Stellen entlang der Küste entnommen wurden, dem Abschussbereich der Feuerwerkskörper am Pier, sowie an zwei lokalen Stränden in der Nähe des Abschussbereiches. Dies geschah am 2. Juli sowie am 4. Juli (eine Stunde nach dem Feuerwerk), um eine genaue Messung bereitzustellen. Zur Analyse der Wasserproben wurde das Pegasus® HRT+ 4D System von LECO, das eine umfassende zweidimensionale Gaschromatografie in Verbindung mit einer hochauflösenden Flugzeit-Massenspektrometrie (GC×GC-HRTOFMS) bietet, verwendet. Das GC×GC-HRTOFMS erwies sich als leistungsstarkes Werkzeug für die Untersuchung, da es eine vollständige, nicht zielgerichtete Analyse der Wasserproben vor und nach dem Feuerwerk ermöglichte und die chemischen Abweichungen zwischen beiden deutlich machte. GC×GC-HRTOFMS konnte auch die Auswirkungen dieser pyrotechnischen Darbietungen und des erhöhten Personenverkehrs in der Nähe der Wasserprobenentnahmestellen auf die Umweltbelastung aufzeigen.

Wie hat sich die Wasserqualität des Lake Michigan durch den erhöhten Tourismus und die Feuerwerke verändert? Die Ergebnisse könnten Sie überraschen...

„Ideen befruchten sich oft gegenseitig, und es kommt zu Kettenreaktionen. Wie bei chemischen Reaktionen können die Ideen in relativ kleinen Bereichen eingeschlossen sein, bevor sie sich allmählich nach außen ausbreiten. Das Silicon Valley in Kalifornien ist ein zentraler Schwerpunkt für Technologie. Für die Massenspektrometrie (MS) ist die englische Stadt Manchester ein Schwerpunkt. In Manchester wurde das erste, außerhalb der USA gebaute, kommerzielle Massenspektrometer hergestellt... “

Ralf Löscher spricht über die neuesten Technologien und die langjährige Erfahrung von LECO auf dem Gebiet der TOFMS-Instrumentierung. Der besondere Fokus dieses Interviews liegt auf der Lebensmittelindustrie und die besonderen Vorteile, die LECO diesem Markt bietet.

„Auf dem Gebiet der chromatographischen Separationstechnologie bietet LECO GC gekoppelt mit Flugzeit-Massenspektrometrie (TOF-MS) an. Dies beinhaltet sowohl eindimensionale als auch zweidimensionale Chromatographie (GC×GC), wodurch die chromatographische Auflösung und Empfindlichkeit erhöht wird. Darüber hinaus ist unsere neueste Technologie im Vergleich zu Triple-Quadrupol-Alternativen zu wettbewerbsfähigen Preisen erhältlich. Außerdem ist die GC-TOF-MS-Technologie für die Analyse von Rückständen in komplexen Matrizen wie Tees, Gewürzen, öligen Produkten, aber auch Babynahrung grundsätzlich unschlagbar.“
