GC Time-of-Flight Mass Spectrometer

Today’s laboratories are being asked to do more everyday—more samples run, more data acquired, more chemical information processed, and more results achieved—all in less time, for less money. With LECO’s Pegasus BT users will get all of the data they need from a single sample run, without the need for additional laboratory support. Unique and powerful software and hardware features simplify quantitation while also identifying more components with increased sensitivity. A StayClean™ ion source virtually eliminates the need for source cleaning, while a convenient benchtop package saves valuable space in the laboratory. The Pegasus BT will give users more uptime, improved chemical data, and an increase in overall productivity and efficiency.
