Exceptional sensitivity

Time-of-flight technology delivers full mass-range sensitivity, all the time. Experience optimized screening capabilities without sacrificing limits of detection.

Extreme durability

Stay running with our innovative StayClean ion source—no source cleaning is required, even after sustained heavy matrix exposure.

Superior chromatography

The Pegasus BTX is a perfect match for hydrogen carrier gas or GCxGC configurations, thanks to its 500 Hz acquisition rate. Pair it with LECO’s QuadJet thermal modulator or Paradigm flow modulator for unsurpassed chromatographic resolution.

Unknowns—resolved

ChromaTOF software’s proprietary deconvolution algorithms produce clean EI spectra for every analyte, delivering accurate library matches, even when presented with multiple coelutions and high-concentration interferences.
