摘　　要：目的建立涉案枪支发射药及其残留物的检验分析方法,并考虑射击的特征化合物。方法使用热分离进样杆进样技术和气相色谱质谱联用仪(TSP-GC/MS)分析方法,研究能实现快速且检测限低的涉案枪支发射药及其残留物的提取方法和介质。结果在数次实验后弹壳中均检测出苯噻唑和二苯胺,论证了这两种化合物可作为是否射击的特征化合物,对涉案枪支发射药特征残留物提取有效,结果可靠。结论 TSP-GC/MS检测方法快速、灵敏,苯噻唑和二苯胺两种特征化合物是否检出可作为判断发射药及其残留物是否存在的依据。Objective To establish a new method for the analysis of gun propellant and its residues in the cartridge case.Method The TSP-GC/MS instrument was used to develop a fast and sensitive method to analyze the gun propellant and its residues, and to find out the characteristic compounds in shooting. Result Benzothiazole and diphenylamine were detected in the cartridge case after repeated trials. Conclusion The established TSP-GC/MS method is fast and sensitive. The fact that benzothiazole and diphenylamine are detected or not can be used as the basis for judging whether the propellant and its residue exist.
