Pegasus BT4D Pegasus BT4D


GC×GC Time-Of-Flight Mass Spectrometer

The Pegasus BT 4D offers enhanced sensitivity by coupling our benchtop Pegasus BT with a high performance GCxGC modulation system. This combination gives the Pegasus BT 4D the ability to interrogate challenging samples where the best sensitivity is needed. Our traditional thermal modulation system provides the highest sensitivity available on the market for those analyzing the most complex samples.  Our new FLUX™ flow modulation system is an excellent option for those looking for added capability over one dimensional GC. 


  • ChromaTOF®, LECO’s exclusive software designed for advance chromatography, works seamlessly with the new Pegasus BT 4D to automatically process user data and remove the guesswork involved with analyte identification and quantification. Features such as NonTarget Deconvolution®, Target Analyte Find, library searches, and an easy-to-configure interface, all come together to give users a better GCxGC experience.
  • Do you know what’s missing in your sample? The Pegasus BT 4D makes is easy to perform a Non-Targeted analysis for complex samples.
  • Clearly identify analytes in your sample with the unmatched sensitivity of the GCxGC modulation process.
  • Our open-style StayClean® EI source virtually eliminates downtime associated with source cleaning, which means more time running samples and less time cleaning your source
