Pegasus GC-HRT 4DHigh Resolution GCxGC-TOFMS

The Pegasus GC-HRT 4D combines the highest performance GCxGC and TOFMS tools on the market with High Resolution Deconvolution (HRD). Ideal for the most complex samples, users are able to find more analytes than ever before and confidently identify unknown components. ChromaTOF brand software, designed specifically for HRT+ instrumentation and GCxGC support, adds advanced qualitative and quantitative capabilities to an all-in-one user-friendly data system.


  • A sleek, benchtop design saves valuable space in the laboratory.
  • Industry-leading sensitivity helps you find and quantify an unlimited number of analytes, while working with proprietary deconvolution algorithms to yield clean, high-quality spectra.
  • Complete historical record of mass spectral components for each sample is retained for future data mining.
  • The tried-and-tested reliability and durability of our Pegasus brand in a convenient benchtop unit.

The Pegasus GC-HRT+ 4D provides the capability to obtain high-resolution mass spectral data using comprehensive two-dimensional gas chromatography (GCxGC). GCxGC provides high peak capacity by trapping compounds eluting from the first chromatographic column and then systematically injecting them into the second column to obtain the second separation. The separation on the second chromatographic phase is completed in seconds, resulting in very narrow chromatographic peaks (<200 milliseconds).

To obtain sufficient data to define a 2D chromatographic peak, acquisition rates of at least 100 spectra/second are required. With the Pegasus GC-HRT+ 4D, data acquisition rates of up to 200 spectra/second can be utilized, giving sufficient data density to obtain spectral deconvolution of the chromatographic peaks. Combined, LECO’s GCxGC chromatography and the Pegasus GC-HRT+ provide the ultimate solution in complex sample characterization.
