微型气相色谱的研究进展

具有高性能、智能化、低功耗、低物耗的分析仪器微型化研究已经是分析仪器的主要发展方向。气相色谱(GC)作为一种应用十分广泛的分离分析仪器,其微型化的研究一直受到科学界和工业界的重视。本文综述了近十几年来微型气相色谱(micro GC)的研究进展。对微型气相色谱的3个主要组成部分,即进样/富集装置、色谱柱和检测器,分别进行了详细的阐述,并简单总结了微型气相色谱的应用现状,对其发展趋势进行了展望。

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.
