Multidimensional Gas Chromatography for Chiral Analysis.

Multidimensional gas chromatography (MDGC) is well-established GC method used for a diverse range of applications. Enantioselective MDGC (enantio-MDGC) has been suggested as the method of preference for the separation of extremely overlapping enantiomers. An extensive number of literatures describe enantio-MDGC of polychlorinated biphenyls, essential oils and flavor and fragrance and amino acids were reported. In this review, the applications of MDGC approaches both, heart cutting GC-GC and comprehensive GC × GC in chiral analysis is presented. Since the application of these techniques in this filed is very broad so it will be divided into sections according to the type of the compounds.
