Comprehensive two-dimensional gas chromatography

This chapter contains information related to the use of comprehensive two-dimensional gas chromatography (GC×GC) for the analysis of compounds contained in food products. General principles, basic theory and practical issues, along with instrumental features, are reported. In particular, and apart from other forms of detection, the use of various forms of mass spectrometry (MS) is described in detail. A series of GC×GC food-related applications (untargeted, targeted and fingerprinting), using both MS and non-MS detectors, are critically discussed.
