毒品及其常见添加成分的拉曼光谱快速分析

摘要

The technique of determining the origin of illicit drugs can provide a large number of useful information for the anti-drug work, thus playing an extremely important role in fighting against drug-related crimes. Determining the source of illicit drugs by analyzing the added ingredients is a significant part of determining the origin of illicit drugs. In this paper, the method of rapid analysis of heroin and methamphetamine and ketamine by Raman spectroscopy is studied; We mix starch, glucose, fructose, sucrose, caffeine, phe-nacetin and paracetamol to illicit drugs with a certain percentage, Whether or not the illicit drug and the added ingredient can be detected in the sample using Raman spectroscopy. Through systematic experiments, the results showed that: using Raman spectroscopy to test the added ingredients and illicit drugs is a rapid and effective method.%毒品来源推断技术可以为禁毒工作提供准确的毒品情报信息,对于有效打击毒品犯罪活动具有重要意义.毒品中添加成分的分析方法研究是毒品来源推断技术的重要组成部分.本文对海洛因、甲基苯丙胺和氯胺酮三类我国常见毒品及其添加成分进行了拉曼光谱快速分析研究,将盐酸海洛因、盐酸甲基苯丙胺和盐酸氯胺酮毒品与淀粉、葡萄糖、咖啡因等添加成分按一定质量比例混合制成混合样本,进行拉曼光谱分析.实验结果表明,在毒品含量低至10％的混合毒品样本中应用拉曼光谱技术能够检出毒品成分；同时在添加成分含量低至10％的混合毒品样本中也能准确检出添加成分.拉曼光谱法是检验常见毒品及其添加成分的快速有效的方法.
