质谱新技术在物证分析中的应用

Applications of new mass spectrometry techniques in analyzing forensic evidence

物证分析对于案件侦破及法庭诉讼均具有重要作用.新兴质谱技术因其直接、快速、灵敏和无损等特点在物证分析中得到广泛应用.本文综述了国内外几种新兴质谱技术在检测爆炸物、违禁药物、潜指纹及真伪文件笔迹等物证中的应用研究实例,并展望了质谱新技术在物证分析方面的发展前景.

Analysis of forensic evidence is very important for detecting and court proceedings. Emerging mass spectrometry techniques are widely used in analysis of forensic evidence, because of the direct, rapid, sensitive and non-consumed detection of the new MS method. This review highlights some forensic applications of new MS method in detecting explosives, illicit drugs, latent fingerprint development of new mass spectrometry techniques in forensic and forged documents. What＇s more, the prospects and applications are also discussed.
