Hollow fiber membrane liquid-phase microextraction technique and its application

中空纤维膜液相微萃取技术是一种集采样、萃取和浓缩于一体,环境友好的样品前处理技术。本文介绍了多孔中空纤维膜的结构特点、微萃取装置以及萃取模式,对影响其萃取效果的因素加以分析,同时介绍了中空纤维膜液相微萃取技术在环境和生物体液等样品中的应用。

Hollow fiber membrane liquid-phase microextraction technique is a kind of environment friendly sample pre- treatment technique, which integrates sampling, extraction and concentration into one. In this paper,the structure characteris- tics of porous hollow fiber membrane, the microextraction installation, the extraction pattern, the applications of hollow fiber membrane liquid-phase microextraction in different samples, such as environmental samples and biological body fluid were intro- duced, and the extraction influential factors were analyzed as well.
