IDENTIFICATION OF VOLATILE CONTAMINANTS OF SPACE CABIN MATERIALS

Fifty-five candidate materials for space cabin construction were stored for 30, 60, and 90 day periods at 23-25C, and 20-40% R.H. in environments of air at a pressure of one atmosphere and oxygen at 5 psia. The composition of the gas-off products were determined by mass spectrometry and gas chromato...

Zusammenfassung:Fifty-five candidate materials for space cabin construction were stored for 30, 60, and 90 day periods at 23-25C, and 20-40% R.H. in environments of air at a pressure of one atmosphere and oxygen at 5 psia. The composition of the gas-off products were determined by mass spectrometry and gas chromatography. Additional analyses were performed on desorbates from four carbon canisters from space cabin simulators and the hydrolysis products of MCS 198.
