Apparatus concentrates contaminants outgassing from specimens in vacuum and passes concentrated contaminants to gas-chromatography/mass-spectrometry system for analysis. Cold wall of collection chamber adsorbs gases from specimen in isothermal cell. When wall heated, plate desorbs gases so they can be analyzed. Collection chamber maintained at low pressure throughout adsorption and desorption process. Determines whether candidate materials for use in vacuum environments generate harmful substances.
