Gas Chromatography with Time-of-Flight Mass Spectrometer - Pegasus 4D GCxGC-TOFMS

The Pegasus 4D GCxGC-TOFMS is a Comprehensive Two-Dimensional Gas Chromatography with Time-of-Flight Mass Spectrometer. GCxGC, combined with the Pegasus HT TOFMS, changes the dynamic when analyzing complex samples. No longer limited to two analytical dimensions, the Pegasus 4D GCxGC-TOFMS system provides you with four dimensions of analytical resolution for a more complete sample analysis. With LECO GCxGC you are able to detect hundreds-to-thousands more compounds than previously seen using conventional one dimensional GC.

It is powerful, easy-to-use Windows-based ChromaTOF, the software simplifies component identification—providing a significant increase in efficiency and productivity. Other unique processing capabilities (such as sample comparisons, peak alignment, and scripting functionality) allow for automated mining of complex GCxGC data to extract previously unidentifiable similarities and differences.


  • Integrated control of all GC, modulator, TOFMS, and auto sampler system components
  • Comprehensive quantitative analysis of target analytes
  • Qualitative analysis with Automated Peak Find and True Signal Deconvolution® algorithms
