[Advances in micro gas chromatography].

Miniaturization of analytical instruments has attracted great attentions both from scientists and industry because of their unique properties such as small volume, high performance, low power and material consumption. Gas chromatograph (GC) is one of the most widely used analytical instruments. Many efforts have been made to develop portable or micro GC for on-line, in-situ and fast analysis in field. In this review, the state of arts in the field of micro GC is summarized. The advances on micro GC including injectors, chromatographic separation columns and detectors are discussed separately. The applications of micro GC are also briefly reviewed. Finally, a prospect on the developments and applications of micro GC is outlined.
