The Next Big Thing in GC-Mass Spectrometry is Here
Pegasus BTX
The BTX is the culmination of nearly 30 years of developing the ultimate TOF mass analyzer for GC and GCxGC applications.
Introducing New TOF Tech
The BTX is the latest generation of LECO’s Benchtop (or BT) GC-TOFMS series. For the past 8 years, the Pegasus BT series has proven reliability in labs performing unbiased, non-targeted analyses and tackling difficult matrices. A diverse spectrum of investigators—including those in industries like Petroleum, Life Sciences, Environmental, Pharmaceutical, Food Safety, and others—have gained deeper insights into the complex chemistries of their samples thanks to the incredible Pegasus BT.
From its predecessor, the Pegasus BTX retains the innovative StayClean® ion source, blinding fast full-spectrum acquisition rates, and 5 orders of linear dynamic range—all seamlessly orchestrated by ChromaTOF® software. A novel ion path and detector design delivers femtogram-level sensitivity in a miniscule footprint—analytes that previously eluded even advanced targeted GC-MS systems are unveiled with rich mass spectra. At LECO, technological innovations never jeopardize our commitment to instrument quality and robustness: that’s why all new BTX systems include a two-year detector warranty, as a testament to LECO’s investments in ion path integrity.

Characterizing Synthetic Aviation Fuels
Characterization of synthetic paraffinic kerosene and traditional aviation turbine fuel is critical to meet regulatory requirements.
The BTX can help obtain commercial approval
Comparing Thyme Aroma Profiles
Volatile and semi-volatile aroma profiles of dried thyme from different countries helps identify chemical differences.
The BTX sniff out the differences.
Screening Targets and Identifying Unknowns
New analytical methods are necessary to monitor increasing levels of per- and polyfluoroalkyl substances (PFAS) in the environment and food chain. BTX expands PFAS analysis.
Unveiling Hidden Aroma in Basil
The BTX's enhanced peak capacity, improved chromatographic separation, and heightened sensitivity can uncover complex low-level aroma profiles.
Non-Target Analysis of Molasses
GC-TOFMS, coupled with advanced deconvolution algorithms, can identify complex aroma profiles of samples like molasses.
