"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."

"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"

"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!"

"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 confi dent that the ion source will remain clean even with dirty samples such as plasma."

"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."

"We send instruments into the harshest of environments and run very demandingsamples 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."
