Hyperadsorptive Atmospheric Sampling Technology (HAST)*
Abstract
*Formerly Sensors. (U) The Hyperadsorptive Atmospheric Sampling Technology (HAST) program will enable exhaustive, accurate, and economical collection of atmospheric trace constituents to support chemical mapping of urban and military environments. The system will demonstrate materials, packaging, and extraction technologies that sample atmospheric impurities whose concentrations range from 10 parts per trillion to 100 parts per million by volume from 100 liter-atmospheres of gas in less than five minutes. New systems to provide rapid, comprehensive, and quantitative trace gas analysis without preconceived lists or libraries of target chemicals will also be developed. The analysis systems will integrate sophisticated separation and spectroscopic techniques with advanced quantum chemistry algorithms to enable library-free identification and ranking (by concentration) of all components present in complex gas mixtures. This capability will revolutionize our understanding of the environment through chemical mapping and reconnaissance. Reproducible analysis of atmospheric samples using sophisticated analytical technology will yield maps of baseline conditions, natural variability, and permit detections of nefarious anomalies involving production, movement, and storage of weapons.
