亚甲二氧基甲基苯丙胺法庭鉴定的化学模式识别研究

Forensic Identification of Ecstasy(MDMA) by Pattern Recognition

目的:利用化学模式识别方法对摇头丸质谱分析数据进行处理,建立一种合适的分析方法,对不同缴获途径的亚甲二氧基甲基苯丙胺进行法庭鉴定。方法:对2 0 0 3年南京市禁毒处所缴获的摇头丸按照案情进行筛选,确定以4例案件中缴获的摇头丸共4 8粒进行气质联用分析,建立模式与识别模型。结果:利用SIMCA法建立了摇头丸法庭鉴定的方法。结论:本文所应用的方法可作为摇头丸法庭鉴定的一种新手段。

AIM:The analytical data of ecstasy(3,4-methylen ed ixoymethamphetamine or MDMA) by GC/MS have been processed using the theory of pa ttern recognition and some suitable method has been built to identify the ecstasy of different captive routes.METHOD :According to the drug case happening in Nanjing,48 grains of ecstasy from the cases whose number is 0398?0024?0328 and 0347 respectively have be en analysed by GC/MS and have been recognized by using the model built by SIMCA .RESULT:The method of ecstasy in forensic identification has bee n built by SIMCA.CONCLUSION:Pattern recognition is an effective method to examine ecstasy in forensic identification.
