A 27-day experiment designed to determine man's contribution to trace contamination in a sealed environment was conducted jointly by the United States Air Force and the National Aeronautics and Space Administration. Direct analysis of the sealed environment was not adequate for this type of comprehensive survey. The use of cryogenic fractionation and concentration, however, did provide samples with sufficient level of contaminants for analysis by means of gas chromatography and mass spectroscopy.
