一种新型固相萃取技术——固相微萃取

A Novel Solid Phase Extraction Method ——Solid Phase Microextraction

固相微萃取技术是９０ 年代初新发展起来的集采样、萃取、浓集、进样于一体的分析技术，具有操作简单易行，不必使用大量有机溶剂，且易实现自动化等优点。本文对该技术的实验方法、原理及其在药物分析、环境保护等领域中的应用进行了综述。

Solid phase microextraction is a simple method without solvent extraction. An extraction phase coated with fused silica fiber was directly immersed into a sample matrix or exposed to the headspace of a liquid or solid sample. SPME integrates sampling , extraction, concentration and sample introduction into a single step. This article reviews the principle and application of the method in some fields, such as in pharmaceutical analysis and in environmental protection.
