The next big thing in gas chromato­graphy-mass spectrometry is here

The PEGASUS® BTX is the culmination of nearly 30 years of developing the ultimate TOF mass analyzer for GC and GC×GC applications.

Introducing New TOF Tech:
The PEGASUS® BTX

The Pegasus BTX is the latest evolution of LECO’s Benchtop (BT) GC-TOFMS series. Building upon the success of the Pegasus BT series over the past 8 years, the Pegasus BTX continues to deliver unparalleled reliability and performance in analytical testing. From unbiased, non-targeted analyses to tackling challenging sample matrices, the Pegasus BTX empowers researchers across diverse industries to gain deeper insights into complex sample chemistries.

It’s very pleasing to have chromatography and software that you recognise. We have data from our BT and we’re comparing that with the Pegasus BTX already seeing increased sensitivity. Interestingly, increased molecular ion information, so abundance of molecular ions in the EI mass spectrum of my Alkanes, which makes determining the molecular weight easier.

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 and 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 GC×GC separation which is perfect for my types of samples.

Key features

Innovative StayClean® Ion Source

The PEGASUS® BTX retains the innovative StayClean® ion source from its predecessor, ensuring continuous high sensitivity without the need for cleaning and minimizing unplanned downtime.

Blinding Fast Full-Spectrum Acquisition

With blinding fast full-spectrum acquisition rates, the PEGASUS® BTX captures comprehensive data sets for thorough sample analysis.

5 Orders of Linear Dynamic Range

Experience enhanced analytical capabilities with 5 orders of linear dynamic range, allowing accurate measurement across a wide concentration range.

Femtogram-Level Sensitivity

A novel ion path and detector design deliver femtogram-level sensitivity, enabling the detection of analytes that previously eluded even advanced targeted GC-MS systems.

Two-Year Detector Warranty

At LECO, our commitment to instrument quality and robustness is unwavering. That’s why all new PEGASUS® BTX systems come with a two-year detector warranty, providing peace of mind and ensuring long-term reliability.

Miniscule Footprint

Despite its powerful performance, the PEGASUS® BTX features a compact footprint, making it suitable for laboratories with limited space.
