Improved Ion Mobility Spectrometer for Chemical Warfare Agents Detection

摘要

On the basis of existing Ion Mobility Spectrometry (IMS) technology, significant improvements have been made in drift tube design, gas path system structure, ionization source choice, and display screen. Then, a series of experiments on Sarin (GB), Mustard gas(HD), Hydrogen cyanide (AC) and VX detection have been launched, whose results indicated that the improved Ion Mobility Spectrometer had good performance in fast response speed, easy rinse, low temperature environment adaption with a high resolution and sensitivity.
