Abstract: Seacoast Science will continue Phase I efforts and fabricate a system for detection and identification of Low Vapor Pressure (LVP) Toxic Industrial Chemicals (TICS). The proposed system will include a microelectromechanical system (MEMS) chemical sensor array, sampling pump and a MEMS preconcentrator optimized for the selective and sensitive detection of a variety of high risk TICS that pose a threat to homeland security. Because of the diverse nature of these compounds we have designed a flexible system that allows for multiple modes of operation. The system will accommodate wall mounted or handheld operation and samples can be introduced from ambient air or by direct input from a swipe. Ultimately this program will yield a small, rugged, lightweight, low-power detection system. In Phase I we began optimization of our MEMS chemicapacitor sensors for some LVPs including a pesticide, explosive and mercury. In a Phase II design reviews we will expand the list of LVP TICS to include other high priority TICs. Our proposed MEMS preconcentrator provides high throughput and high collection efficiency while using minimum power. In Phase II we propose to integrate our sensors, a preconcentrator and a sampling system and to evaluate the system by exposures to LVP TICS.
