综合运用仪器分析方法快速检验烟火剂
|
摘要
为快速判断警方缴获的疑似爆炸物质是否为烟火剂,改进了烟火剂的常规检验方法,综合运用扫描电镜/能谱仪、气相色谱/质谱联用仪、傅里叶变换红外光谱仪对检材进行了快速检验,准确地检出了高氯酸钾、硝酸钡、硫磺、铝粉、镁粉成分,推断该物质为烟火剂。本研究为此类案件的侦查提供了一种方法。
In order to determine the composition of suspected explosives in some case, the original inspection methods for pyrotechnics were improved, scanning electron microscopy and X-ray energy disperse spectrometer(SEM/EDS), gas chromatography mass spectrometer(GC/MS)and Fourier transform infrared spectroscopy(FTIR) were comprehensive applicated to analyze compounds in grey powders from an explosive case. Then, potassium perchlorate, barium nitrate, sulphur aluminite and magnesium powder in pyrotechnic samples were determined. The study provides a determination method for such case inspection.
