The purpose of this work was to determine microcontaminants in a sealed environmental system. The separation and identification of the collected samples were accomplished with gas-liquid chromatography and infrared spectrophotometry. Fifth-four sets of samples of the atmosphere from a Brooks Air Force Base space cabin simulator, comprising 162 individual samples, were analyzed. The method used was gas-liquid chromatography using a flame ionization detector. The retention time on the column was used for identification, while the peak area was used for quantitative estimation of the compounds. A collection of the vapor infrared spectra of 146 compounds, which are possible contaminants for space cabin simulators, has been compiled during the 2 years of this contract. A computer program for sorting infrared spectra with the aid of the ASTM deck of infrared cards has been established. Analyses have been made of gases evolved from paint panels, from the decomposition of a Teflon insulator, and from human waste products. Author
