Abstract
Gas Chromatography separates components in time. Mass spectroscopy provides information that aids in the identification and structural elucidation of each component. Comprehensive 2-Dimensional gas chromatography (GC×GC) is a novel technique. The revolutionary aspect of GC x GC, with respect to classical multidimensional chromatography, is that the entire sample is subjected to two distinct analytical separations. The resulting enhanced separating capacity makes this approach a prime choice when GC analysts are challenged with highly complex mixtures. The combination of a third mass spectrometric dimension to a GC x GC system generates the most powerful analytical tool today for volatile and semi-volatile analytes. The present review is focused on the instrumentation of 2D GC-MS, the difference between GC and 2d GC, application of 2d GC-MS have been discussed.
