摘　　要：固相微萃取(SPME)是近年来发展起来的集采样、萃取、浓缩、进样于一体的综合技术。SPME在司法化学鉴定领域有着很好的发展前景,它的主要优点是分析速度快、方法简便、无需溶剂、灵敏度高、所需样品体积小,易于实现仪器化和自动化,适用于现场分析。SPME在司法化学鉴定中的应用十分广泛,用于可燃性的液体残留物、残留爆炸物、生物样品中的毒、药物以及其他物质分析。本文主要对SPME技术及其在司法化学鉴定中的应用与进展做一综述。Solid phase microextraction (SPME) is a techniquethat integrates sampling, extraction, concentration and sample in-troduction into a single step. SPME has been developed in recentyears, which will has a good development in forensic analysis. SPMEis often faster than traditional techniques; can be readily automated;allows for multiple sampling, preservation of the sample, eliminationof solvents, and minimization of the risk of sample contamination bythe reason of the simplicity of the technique. SPME can be applied tospot analysis. The SPME comprehensive applications covered inforensic analysis include ignitable liquid residues (also referred to asaccelerants), explosive traces, drugs and poisons from biologicalspecimens and other forensic applications. This review summarizesthe technique(SPME), and its applications and development inforensic analysis.
