摘要
文章总结了射击残留物(Gunshot residue,GSR)提取方法的研究现状,对目前常用的提取方法进行了分类总结,并对其灵敏度、选择性、适用范围等进行了阐述,以有机和无机的成分视角对射击残留物的成分进行了分类汇总,并在此成分分类的基础上分别阐述了有机射击残留物(Organic gunshot residue,OGSR)和无机射击残留物(Inorganic gunshot residue,IGSR)当前流行的检测方法,包含其原理、使用范围、灵敏度、优缺点,总结了金属有机框架作为无重金属GSR的分析提供的新的研究路径的发展。最后,本文对射击残留物未来的研究方向进行了展望。
The article summarizes the current research status of extraction methods for gunshot residue(GSR),classifies and summarizes the current commonly used extraction methods,and describes their sensitivity,selectivity,and scope of application,etc.On the basis of this classification,the current popular detection methods for organic gunshot residue(OGSR)and inorganic gunshot residue(IGSR)are described,including their principles,scope of use,sensitivity,advantages and disadvantages.The novel method of metal-organic framework as a marker for gunshot residue provides a new approach for the analysis of heavy metal-free CSR.With the advancement of technology,GSR analysis will rely more on highly sensitive and selective analytical techniques,while the research and application of novel markers is another key to the development of the court science field.
