Chemical Reconnaissance
Abstract
The Chemical Reconnaissance program enabled exhaustive, accurate, and economical collection of atmospheric trace constituents to support chemical mapping of urban and military environments. The system demonstrated materials, packaging, and extraction technologies that sample atmospheric impurities with concentrations ranging from 50 parts per trillion to 50 parts per million by volume, from 100 liter-atmospheres of gas, in less than five minutes. The analysis system integrated high-resolution separation and spectroscopic techniques with automated analysis software to enable identification and ranking (by concentration) of all components present in complex gas mixtures. Reproducible analysis of atmospheric samples using sophisticated analytical technology yielded data for baseline conditions, natural variability, and permit detections of nefarious anomalies associated with production, movement, and storage of weapons, even under shifting backgrounds driven by meteorological and seasonal events.
