Comprehensive Two-Dimensional Gas Chromatography

The GCxGC offers you the resolving power of a GCxGC system combined with advanced ChromaTOF® software for an increase in efficiency and productivity for samples that are too complex for a single-channel detector system. Ideal for everyday quality control and production needs, these GCxGC systems provide you with all the tools necessary to achieve exceptional results.

Transfer analytical methods developed on your Pegasus 4D GCxGC-TOFMS to a cost-effective GCxGC system for routine analysis.

  • Flame Ionization Detector (FID) and Electron Capture Detector (ECD) models available


Two-dimensional gas chromatography occurs by the repeated and re-injection of effluent from one chromatographic column into a second column of orthogonal phase. The cycle of refocusing and re-injection is matched to the time required for compounds to elute from the second GC column, resulting in separation of compounds across a plane, rather than just along a line. With our GCxGC system this is accomplished with a dual-stage, quad-jet thermal modulator positioned between the two columns.
