4. GCxGC or two-dimensional integral gas chromatography
4.1 Principle
GCxGC (comprehensive two-dimensional gas chromatography) is an analytical technique that emerged in the early 1990s . The special feature of this technique is that volatile compounds are separated by two capillary columns, placed one after the other in the oven(s) of a chromatography unit, and coupled by a modulation system. As already mentioned, this technique involves passing the entire 1D chromatogram onto a secondary (2D) column. This feat is only made possible by modulating the 1D effluent, i.e....
