Abstract

Southwest Sciences Inc. (SWS), in collaboration with the Southwest Research Institute (SwRI), will develop a reliable, ultra compact, low power diode laser multigas sensor to measure carbon dioxide (CO2), ammonia (NH3), oxygen (O2) and water vapor (H2O) concentrations in the presence of saturated and condensable water concentrations appropriate for NASA's portable life support system (PLSS). A high sensitivity optical absorption technique known as wavelength modulation spectroscopy will be used in the sensor. The system will be light weight (
