火灾现场残留汽油成分检验研究综述

Progress toward the determination of residual gasoline component on fire scene

综述了近几年国内外法庭科学领域对于火灾现场残留汽油成分检验的研究进展。简要介绍采取加热挥发进行汽油残留物的快速鉴别方法,包括微量残留汽油提取技术的进展,气相色谱-质谱联用技术结合化学计量学方法对于残留汽油成分分析识别的研究进展。同时介绍了火灾现场残留汽油成分检验领域的一些新的探索思路,并对该领域的发展作了简要展望。

Progress of the examination of residual gasoline components on fire scene in the field of forensic science at home and abroad in recent years was reviewed.The fast determination of residual gasoline component through heating and volatilization was introduced briefly.The main contents include：advance of trace residual gasoline extraction technology;progress of gas chromatography-mass spectrometry combined with chemometric methods for identifying residual gas composition analysis.Meanwhile,some new ideas of test of the residual gasoline component on fire scene were introduced and prospect on this field was briefly discussed.
