Handheld FT-IR/Photoacoustic Chemical Agent Detector

Manning Applied Technology proposes development of the MP-100 handheld FT-infrared photoacoustic chemical agent detector, following a highly successful Phase I effort. Chemical attacks and accidents can be mitigated partially by cost-effective sensors. High priority programs will benefit from a sensor compliant to Joint Warning & Reporting Network (JWARN) standards. The device is ideally suited to detection of airborne chemical agents and TICS, at 1 to 100 parts per trillion, well below permissible exposure limits. The MP-100 is modular, rugged, compact and inexpensive (~$1500 each). A vapor preconcentrator is integrated with photoacoustic detection using high-sensitivity MEMS microphones. A novel field-widened interferometer provides high throughput of infrared energy. A computer-machined aluminum housing and COTS handheld computer complete the system. Dr. McClelland will manage integration of the photoacoustic cell and MEMS microphone. Dr. Manning, the Principal Investigator, is an internationally recognized spectrometer design expert. Military applications include a variety of sensing activities for personnel protection. Commercial applications include a wide range of process and quality control, medical, environmental monitoring, laboratory research, field measurements and remote sensing applications. Conservative estimates are a $10 million per year market, with the low cost insuring significant market share. Several partners will provide Phase II and III support.
