Abstract

The need for reliable, quick-acting low-cost detectors for chemical warfare (CW) gases is evident, and many sensors systems have been proposed 1,2. Mobile and hand-held battlefield CW sensor systems are already deployed, but their high cost prevents their widespread use in homeland security applications. CW monitoring requires rapid and certain identification of agents and agent class compounds with high sensitivity and selectivity in order to avoid non-detection or delayed response. Differentiation from similar commercial chemicals is also essential, as false alarms will degrade the confidence in these sensors. In this communication, we seek to illustrate aspects of the methodology that could be employed for developing fast CW warnings based on solid-state micro-sensors, and signal processing methods that could be integrated into custom-made electronic devices that efficiently use only the most relevant inputs necessary for positive agent identification.
