Abstract

Gas chromatography, in which a gaseous moving phase is passed over a liquid or solid stationary phase within a column, is one of the most widely used instrumental analysis techniques today. This article provides a basic overview of gas chromatographic theory, instrumentation and technology. Descriptions of common modes of gas chromatography: packed and capillary columns, inlets, columns, detectors, data systems, multidimensional separations and fast GC are provided. The text is heavily referenced to major texts and research articles for further study.
