"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."

"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."

"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."
