This review article focuses on advances and technical developments of the realm of membrane extraction techniques for the analytes that are (made) amenable to gas chromatographic analysis, and sheds light on the analytical applications to biological and environmental samples. In this review, the state of the art in this growing area of membrane extraction for gas chromatography is presented and several selected examples from our work and that of other groups are discussed. The published articles on the techniques and their applications, found in the scientific literature between the years 2000 and May 2007 and cited in over than 100 references, are perused and commented. A good deal of light will be thrown on the novelty of the techniques, instrumentations and applications. The mentioned techniques are mainly microporous membrane liquid-liquid extraction, extracting syringe, two-phase hollow-fibre-protected liquid-phase microextraction and its modifications, and membrane extraction with sorbent interface and its variants. The merits and demerits of the techniques will be highlighted.
这篇综述文章聚焦于适用于气相色谱分析的分析物的膜萃取技术领域的进展和技术发展，并阐明其在生物和环境样品分析中的应用。在本综述中，介绍了气相色谱膜萃取这一不断发展领域的最新技术水平，并讨论了我们团队以及其他团队工作中的几个选定示例。查阅并评论了2000年至2007年5月期间发表在科学文献中、被100多篇参考文献引用的关于这些技术及其应用的文章。将对这些技术、仪器和应用的新颖性进行大量阐述。上述技术主要包括微孔膜液 - 液萃取、萃取注射器、两相中空纤维保护液相微萃取及其改进方法，以及带有吸附剂界面的膜萃取及其变体。将突出这些技术的优缺点。
