LECO PEGASUS BT GC-TOFMS

The Pegasus BT GC-TOFMS is a compact, high-performance benchtop gas chromatography time-of-flight mass spectrometer designed to deliver comprehensive chemical information with exceptional sensitivity, speed, and reliability. It combines advanced TOF mass spectrometry hardware with LECO’s powerful ChromaTOF® software to support both routine and advanced analytical workflows.

LECO PEGASUS BT GC-TOFMS

Designed for laboratories that need to analyze more samples, generate more data, and achieve results faster, the Pegasus BT acquires full-range mass spectral data in every run—ensuring that no analytes are missed, even in highly complex matrices. Industry-leading sensitivity, combined with NonTarget Deconvolution® (NTD®), enables confident identification and quantification of both known and unknown compounds by effectively separating co-eluting peaks and minimizing matrix interferences.

LECO PEGASUS BT GC-TOFMS: NonTarget Deconvolution® (NTD®) Automated deconvolution ensures that coeluting peaks and matrix interferences don't hinder your analyses.StayClean Ion Source Open-style EI source virtually eliminates downtime associated with source cleaning*, which means you can spend your time running more samples. *Even after 3,000 sludge injections, source has not needed cleaning.

The system features LECO’s proven StayClean® open-style EI ion source, which virtually eliminates downtime associated with source cleaning and allows extended operation even with challenging sample matrices. Its compact benchtop footprint makes the Pegasus BT an ideal solution for laboratories with limited space, without compromising analytical performance.
