(Chemical agent) point detection system (IPDS) employing dual ion mobility spectrometers

摘要

A system for sampling the ambient air of a selected environment for the presence of unwanted chemical vapors, such as nerve or blister gases includes an external air sampling unit and a detector unit having first and second ion mobility spectrometers which simultaneously detect and monitor for the presence of the chemical agent vapors so as to provide an accurate and quick determination of the unwanted chemical vapor within the selected environment.
