摘要
固相微萃取技术(SPME)是一种新型的样品前处理方法,它可一步完成取样、萃取 和浓缩,简化了传统前处理方法的繁琐步骤,而且不会造成二次污染。因此,SPME技术在短 短几年内已广泛运用于各个研究领域。本文对SPME技术的原理作了简要介绍,对目前的应用 研究情况作了初步的总结,并对今后的发展趋势作出了预测。
Solid phase microextraction is a new technique for sample pretreatment.It is a single-step process that includes sampling,extra ction and concentra tion,which leaves out the complicated steps of the traditional techniques.In ad dition,it will not cause secondary pollution.Therefore the technique has been applied in a wide range of fields during the past few years.This paper reviews the recent references and theory,present applications and future developments of SPME are discussed.
