Leco - Chromatography - GC - TOFMS

Find and quantify an unlimited number of analytes, in every run, every time you use Leco GC-TOFMS. Complete historical record of mass spectra components for each sample for future data mining. You will no longer suffer spectral distortion-based MS analysis. Purified spectra can be used for targeted compound identification. Reliability and durability that have been tested over time with low-maintenance source, which practically eliminates downtime.

Available models


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.

Pegasus GC-HRT

Now even more sensitive, the Pegasus GC-HRT+ was developed to withstand the rigor of modern high performance analytical demands, the Pegasus GC-HRT+provides the ultimate high-performance MS capabilities. These capabilities include industry leading mass accuracy, full mass range acquisition with exceptional speed, isotopic abundance and mass resolution, all available within 1 injection.

LECO's own Folded Flight Path® (FFP®) technology and novel data acquisition system enables resolution of 50,000 FWHM, mass accuracies less than 1 ppm, and acquisition rates up to 200 spectra/second—all with the goal to facilitate rich analyte finding and high-confidence analyte identification.
