LECO provides innovative and timesaving analytical instrumentation for the analysis of organic Carbon content.
Specific Advantages Including
- Market leading analytical performance
- Simplified sample preparation
- Robust & reliable instrumentation
- Unsurpassed instrument flexibility
- Adhering to all the current standards, such as ISO 10694, BS EN 17505 and EN 15936
Instrument Portfolio for TOC Analysis
CS744 // Carbon analysis by combustion
Redefine the way you determine carbon in soils and plant tissues with our 744 series. Using extensive customer feedback and innovative engineering, the 744 takes advantage of our immersive CORNERSTONE® brand software platform and a number of features, ...
... such as an improved IR cell design and available automation, come together to increase usability, lab productivity, and lower your cost-per-analysis.
RC612 // Multi-Phase Carbon And Water Determination
Get fast, reliable carbon and water determination with our RC612. The RC612 is a resistance furnace multiphase carbon and moisture determinator which quantifies the carbon and moisture present in soils and plant tissues and illustrates the source of several types of carbon.
The RC612 features a state-of-the-art furnace control system, which allows the temperature of the furnace to be stepped and ramped from near ambient to 1,100 °C, in either oxidative or reductive carrier gas. The RC612 utilizes an afterburner furnace that ensures complete combustion of volatile species released at lower primary furnace temperatures.
SC832 // Sulfur And Carbon Analysis
LECO’s 832 series of Elemental Determinators are specifically designed to perform carbon and sulfur analysis of soil, plant tissue and other organic and some inorganic materials. The 832 series is a valuable resource for any laboratory needing fast and accurate analysis.
Request SC832
Methods of TOC analysis include
1. Acid Digestion Method
The most common method for determining TOC is the acid digestion method. By acid treating a sample, usually with hydrochloric acid, which is strong enough to react with inorganic carbonates but does not react much with organic Carbon, the inorganic carbonate species within the sample will effervesce as Carbon dioxide. The acid-treated sample and a non-acid-treated sample can both be analyzed using either the LECO C744 series or LECO C832 series for Carbon content. The untreated sample would indicate the total carbon content, while the acid-treated sample’s Carbon content would be the remaining organic Carbon content. The difference between the two samples would be the total inorganic Carbon (TIC) content.
2. Temperature Dependent Method
Another Carbon determination method is temperature dependent. With the temperature dependent method, samples do not need to be pretreated. Organic Carbon combusts to CO2 between 150 °C and 450 °C, while inorganic species combust below 1,000 °C. The RC612 resistance furnace multiphase Carbon and moisture determinator performs this analysis by using a two-step temperature ramping at 450 °C and 1,000 °C without any acid pretreatment of the samples. The CO2 gases are swept through to an NDIR at 450 °C and again at 1,000 °C to determine the TOC and TIC in the sample.
For a more comprehensive exploration of these two methods, as well as an in-depth comparison of LECO instrumentation, please contact us:

► App Note | Characterizing Extractables by GC×GC & HR-TOFMS
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.
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

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.
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

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.

LECO-Lösungen für MOSH/MOAH
Was auch immer Ihre Anforderungen an die Probenvorbereitung sind, nutzen Sie die Leistungsfähigkeit der LECO GCxGC und TOF-Technologie, um die komplexen Herausforderungen der MOSH/MOAH-Analyse zu lösen.
Als die Kaunis-Eisenmine in Schweden eröffnet wurde, war sie die modernste Einrichtung in einer der wichtigsten Branchen Schwedens. Die Mine beauftragte das Degerfors Laboratory (D-LAB) mit der Eisenanalyse. Bevor die Proben analysiert werden konnten, musste das Erz jedoch getrocknet und der Feuchtigkeitsgehalt bestimmt werden.
D-LAB hatte nun ein Problem: Ihre bisherige Methode zur Feuchtigkeitsbestimmung nutzte eine manuelle Waage, die jeweils nur eine Probe verarbeiten konnte und alle fünf Minuten von einem Techniker bedient werden musste. Der eingesetzte ISO 3087:2020-Standard war ebenfalls ein Problem, da ein einzelner Durchlauf über 5 Stunden dauern konnte. Das Labor wandte an LECO und fragte nach einer Lösung.
LECO-Lösungen für die Energie- und Kraftstoffanalyse
Die Erweiterung, Erhaltung und Ausweitung der Verfügbarkeit unserer begrenzten Energieressourcen bedeutet, dass Unternehmen in der Lage sein müssen, neue Quellen zu analysieren und die Qualität bestehender Vorräte zu validieren. Die Lösungen von LECO ermöglichen es Energieunternehmen, die immer strengeren EPA-Vorschriften einzuhalten.
Während LECO weiterhin führend bei der Prüfung von Kohle und Koks auf Kohlenstoff/Schwefel ist, hat das Unternehmen seinen Schwerpunkt seitdem auf Biokraftstoffe, Zusatzstoffe, Diesel- und Erdölprodukte sowie Kerosin ausgeweitet. Da diese Ressourcen immer wertvoller werden, ist die LECO-Technologie zur Stelle, um Potenzial und Qualität zu validieren und Ihnen zu helfen, behördliche Vorschriften einzuhalten.

Im Rahmen der Feierlichkeiten zum 30-jährigen Jubiläum von LECO im Jahr 2021 wurde das neue LECO-Büro in Pilsen eröffnet.
Die Dumas-Methode bietet gegenüber der Kjeldahl-Methode mehrere Vorteile: Sie ist viel schneller, bei viel niedrigeren Betriebskosten, hat keine echten Sicherheitsprobleme und erzeugt keinen Giftmüll. Es gibt jedoch eine Debatte darüber, welcher der beiden Hauptansätze für die Dumas-Methode besser ist: ein vertikaler oder ein horizontaler Verbrennungsofen. Um die Frage zu klären, welche Methode präziser ist und mehr Vorteile bietet, analysierten LECO-Chemiker viele Probentypen mit dem FP828 und dem FP928.
Für weitere Informationen und eine detaillierte Aufschlüsselung der Ergebnisse sowie einen Blick auf die Proben, die in diesem Experiment verwendet wurden, lesen Sie den Artikel von Michael Jakob in der September 2021 Ausgabe von eFOOD-Lab International.
Mikroplastik ist überall auf der Welt allgegenwärtig und findet sich inzwischen im arktischen Schnee und antarktischen Eis – und überall dazwischen. Es gibt Billionen von Mikroplastikpartikeln, die auf dem Oberflächenwasser schwimmen, und jeder, vom Säugling bis zum Erwachsenen, nimmt täglich Dutzende bis Zehntausende dieser Partikel auf.

Die thermogravimetrische Analyse (TGA) ist seit Anfang des 20. Jahrhunderts bekannt, und obwohl die Technologie weit fortgeschritten ist, blieben die Grundprinzipien bis heute gleich. Die TGA erfasst Änderungen der Reaktionsgeschwindigkeit zu spezifischen chemischen und physikalischen Eigenschaften eines Materials als Funktion von Temperatur oder Zeit, um so das Probenmaterial zu beurteilen. Die meisten TGA werden heutzutage entweder als Mikro-TGA (mit Proben in Milligrammgröße) oder Makro-TGA (mit Proben in Grammgröße) durchgeführt.
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.
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.

So many factors go into the quality and characterisation of plants and biomass, but many thermogravimetric analyses take so much time. Drying, ashing, and weighing multiple samples takes effort and care just to control for atmospheric effects, much less to actually get precise results that can then be used to analyse the quality and structure of the plants. LECO's TGA801 is an automated thermogravimetric analyser designed to take the time out of the testing.

The past year with the rise of Covid-19 around the Earth has been a challenge to all of us. See how our European subsidiaries dealt with the pandemic around Europe and how our customer support and other services adapted to these new situations in the different countries. Click on the countries to see our personal experiences!

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.”
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…
Lennart Schwartz, Ph.D, Sales Director Nordic Region, LECO Nordic AB
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.
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!
Leticia García, Commercial Director, Spain & Portugal
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…

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.
For a more detailed breakdown of the analysis of these oils and how the GC×GC separation provides a huge advantage in the characterisation and comparison of these samples, fill in the form and check out our application note.

Haben Sie den letzten Artikel im Food Navigator gelesen ? Zur Bestimmung des Proteingehalts in Lebensmittel ist es notwendig den Stickstoffgehalt zu analysieren. Die Bestimmung von Stickstoff mittels klassischer Nasschemie ist langsam und zeitaufwendig. Die auf Verbrennung basierende Dumas-Methode hat in den letzten Jahren an Popularität gewonnen, da sie die Laborproduktivität erheblich steigert. Weist die Probe jedoch einen niedrigen Stickstoffgehalt auf, kann die Analyse schwierig sein. Beispiele für diese schwer zu analysierenden Proben sind trockene Maisstärke, NDIN-Filterbeutel, Nahrungsergänzung und Bier. Wie kann die Verbrennungsmethode optimiert werden, um diese niedrigkonzentrierten Stickstoffproben korrekt zu analysieren?

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.
Soil is the material where corn grows. This sounds to be a simple sentence, but keep in mind, that a big part our food is directly or indirectly coming from plants that are sown, grown and harvested in agricultural soil. For modern agriculture especially when including environmental concerns, the chemical analysis delivers very important parameters for a complete characterisation of soil. LECO is the specialist for CNS and moisture/ash analysis in soil, as well as for Carbon species analysis like TOC/TIC or according to EN 17505 TOC400, ROC, ROC900 and TIC 900.
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.

Eine genaue Bestimmung des Feuchtigkeitsgehalts in Milchprodukten liefert wichtige Informationen in Bezug auf die Lebensmittelqualität und -sicherheit (Textur, Geschmack, mikrobielle Stabilität). Feuchtigkeit ist auch eine Schlüsselvariable zur Berechnung der Reinheit, Ausbeute und/oder für die Analyse der Produktbestandteile auf Trockenbasis.
Das TGM800 bietet dem Benutzer flexible Methodeneinstellungen, Automatisierungs- und Hardwarefunktionen, die die Effizienz, Produktivität und Analyseleistung der Feuchtigkeitsbestimmung maximieren. Dies wird neben der Möglichkeit erreicht, die Anforderungen des primären Trocknungsverlustverfahrens für die Probe zu erfüllen.
