摘要
提出了用X射线光电子能谱法(XPS)对某爆炸案件的爆炸残留物进行定性、定量分析,同时以X射线荧光光谱仪(XRF)、扫描电镜能谱仪(SEM/EDX)为辅助测试手段,判断为氯酸盐类炸药,所用炸药为烟火剂。结果表明:XPS可以无损、快速地检测出无机爆炸残留物的元素成分及含量,并确定主要爆炸成分的化学式,进而确定罪犯所用炸药的种类,为侦破案件提供线索。
X-ray photoelectron spectroscopy（XPS） was used in the qualitative and quantitative analysis of explosive residues remained in an explosion case assisted with X-ray fluorescence spectroscopy（XRF） and scanning electronic microscopy energy dispersive X-ray analysis（SEM/EDX）.It was judged that the explosive is pyrotechnic composition,which belongs to chlorate explosives.It was shown that by XRS the elemental composition and content of inorganic explosive residues could be detected non-destructively and quickly,and the chemical formula of the main explosive component could be determined.The determination of the type of explosives used by the criminal would provide clues for the investigation of explosion cases.
