Analysis and composition of a model trace gaseous mixture for a spacecraftGrowing concern over trace gaseous contaminant accumulations in the enclosed atmospheres of long duration spacecraft missions has prompted the development of a trace contaminant data base on the basis of gas, lithium hydroxide, and charcoal samples collected on Space Shuttle missions. A model trace contaminant gas mixture containing 14 compounds was chosen with the aid of a FORTRAN program, on the strength of contaminant chemical and toxicological categories, frequency of occurrence, and worst-case concentration. The model gas mixture can be used to test trace contaminant control hardware for a manned spacecraft environment.
