摘要
对射击残留物中微量元素的传统成分从无机成分和有机成分角度进行了分类总结,介绍了新型的发光的射击残留物成分(Luminescent GSR,LGSR)和聚合物成分,以及新型的头发、鼻腔采样样本,从无机成分和有机成分角度对传统仪器分析方法进行了分类总结,包含各种方法的原理、适用性、可靠性、灵敏度、局限性以及操作时的注意事项,同时还总结了近五年较为突出的新型检验方法的开发和应用,包括仪器的检测限度、样本制备、样本损失以及在一台仪器中同时分析射击残留物的有机成分(Organic Gunshot Residues,OGSR)和无机成分(Inorganic Gunshot Residues,IGSR)的能力以及与传统方法的比较。检验人员可根据需要检验的成分特点和应用需求选择适宜、高效的方法。
The basic classified and summarized the traditional components of trace elements in GSR from the perspectives of inorganic and organic components,introduced new luminescent gunshot residues components(LGSR)and polymer components,as well as new hair and nasal samples.We classified and summarized the traditional instrumental analysis methods from the perspective of inorganic and organic components,including the principles,applicability,reliability,sensitivity,limitations,and precautions of various methods.We also summarized the development and application of prominent new inspection methods in the past five years.They included the detection limits of the instruments,sample preparations,sample losses,and the ability to simultaneously analyze Inorganic GSR(IGSR)and Organic GSR(OGSR)in one instrument,as well as comparisons with traditional methods.The inspectors can choose an appropriate and efficient method according to the characteristics of the ingredients to be inspected and the application requirements.
