摘　　要：样品前处理是整个分析过程中的关键环节,传统的样品前处理技术需消耗大量萃取溶剂、操作繁琐且难以实现自动化。固相微萃取技术是一种新型无溶剂的样品前处理技术,集采样、萃取、浓缩和进样于一体,具有无萃取溶剂、可直接进样、操作简便快捷、灵敏的特点。本文简述了固相微萃取技术的基本原理,综述了近几年固相微萃取技术在苯系物分析中的应用,并对其发展前景进行了展望。Sample pretreatment technologies are crucial step in analysis process. Traditional sample pretreatment technologies need large volume of extraction solvent,complex and hard to be automatic. Solid phase microextraction technology is a novel sample pretreatment technology with advantages of solvent free,directly injection,simple operation,and sensitive. The basic theory of SPME was introduced,and the applications of SPME on the analysis of benzene series were summarized. Furthermore,the development prospect of SPME was also introduced.
