用于毒品和爆炸物现场检测的双路IMS痕量探测仪研究

摘要

The ionization of drugs and explosives can produce positive and negative ions for each in IMS, so different directions of electric field in the drift tube is needed to detect them all. The methods of detecting both drugs and explosives at the same time in IMS are discussed detailedly in this paper. And the various drugs and explosives were detected by our dual drift tube experiment system.%在离子迁移谱检测技术中毒品和爆炸物离化产生的离子极性不同,因此需要不同方向的迁移电场来完成对这两类物质的探测.该文对毒品和爆炸物单次同时检测的实现方法作了较为详细的探讨,并对其中一种方法进行了实验验证.
