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.

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

A portable system for sampling the ambient air of a selected environment for the presence of unwanted chemical warfare vapors, such as nerve or blister gases, is disclosed. The excitation for the electrical elements of the system can be originated from a battery or from an ac excitation. The system comprises 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, without false alarming to non-chemical warfare agent vapors, which act as interferents. The system design also allows monitoring in the presence of electromagnetic interference (EMI).
