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.
See Everything, All the Time
Collect full mass range data, even when performing targeted analyses. Never miss another clue.
Advanced Deconvolution Algorithms
Even in the densest of matrices, uncovering analytes is easier than ever with the help of clean spectra.
Say Farewell to Source Cleaning
Stay running with the StayClean® ion source, which requires no cleaning, even after sustained heavy matrix exposure.
Sensitivity in Spades
Trace-level detection with helium or hydrogen carrier gases – no analytes escape detection.
Introducing New Time-of-Flight Technology
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.

Working in omics applications, I really need instrument data that is sensitive as well as robust and offers the possibility to do non-targeted analysis. To be honest, so far, this is exactly what we get with the new Pegasus BTX. After testing food and biological matrices on it, I can see that the system is highly sensitive and providing all the added value of the GCxGC separation, which is perfect for my types of samples.
