Cryogenically Trapped Trace Contaminants Analyzed by Ionizing Gas Chromatography

Abstract

The purpose of this work was to determine quantitatively the concentration of microcontaminants in a sealed environmental system. The separation and identification of the cryogenically trapped trace contaminants were accomplished with liquid gas chromatography using a flame ionization detector. Thirty-nine sets of samples were analyzed, each set consisting of 3 cylinders. Nine sets of samples were taken during a manned simulator run conducted at Brooks Air Force Base in October to November 1965, 29 sets from a similar run conducted in March to April 1966, and one sample set from a trapping efficiency run. The compounds contained in the sample cylinders were identified by their time of elution from a column and the amount measured with the aid of peak areas. The response characteristics of the chromatography were calculated from responses obtained with standard mixtures.
