GC×GC Applications Guide
The benefits of comprehensive two‑dimensional gas chromatography for a range of applications
30 Sept 2019GC×GC first attracted attention in the late 1970s, but for many years advances in conventional GC–MS meant that its superior separation capacity was not seen as being worth the additional technical complexity.
Thanks to greatly improved hardware and software, this has changed, and as a result GC×GC is now being routinely used in a variety of fields. This guide demonstrates just some of the most important applications.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.

Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
