固相微萃取及其在环境分析中的应用

Solidphase microextraction(SPEM)and application on environmental analysis

本文系统地阐述了一种新型的样品制备方法——固相微萃取的原理及其在环境分析中的应用。该法的优越之处在于可一步完成取样、萃取和浓缩。操作简便、快速且易于实现自动化。

The principle and application on environmental analysis of a new sample methodsolid phase microextraction(SPME)are introduced in this paper.This method is very simple,fast and easy to automate.It is a singlestep process that sampling,extraction and concentration are focused in a single step.The technique can be used for the pretreatment of both polar and nonpolar organic compounds.
