Mass Spectrometer Analysis of Gases in Blisters in Glass

JSGT 1956 V40 T032-T038

An apparatus used to break open single blisters in a vacuum and to analyse the gas content with a mass spectrometer is described. Condensation analysis is used to obtain a check on the mass spectrometer results. The pressure in the blister prior to breaking can be calculated from the data. The results of some typical analyses are given.
