EXP-SA IMS-MS for the Detection of IEDs

0731306 hill这项工作的目的是解决单独使用IMS检测爆炸物的相关问题。IMS因其灵敏度高、便携性好，一直是爆炸物和化学武器领域最常用的检测方法。然而，由于化学干扰，IMS容易出现假阳性。该研究计划描述了几种方法，不仅提高了IMS的分辨率，而且通过使用质谱检测和选择性电离方法增加了额外的选择性标准。使用两种正交分析方法有可能减少误报。

0731306HillThe objective of this work is to solve the problems associated with explosives detection by IMS alone. IMS has always been the most popular method for explosives and chemical weapons detection in the field due to its sensitivity and portability. However, IMS has been prone to false positives due to chemical interferences. The research plan describes several approaches to improve, not only the resolution of IMS, but to add additional criteria of selectivity by using mass spectrometry detection and selective methods of ionization. The use of two orthogonal means of analysis has the potential for the reduction of false positives.
