Abstract : A thermocouple assembly was set up in order to measure in a satisfactory manner the temperature of microcrucibles used in a mass spectrometer for the study of solid or liquid compounds below 1100 K. The vapor tension and latent heat of sublimation of copper and silver were measured by mass spectrometry. The values for the latent heat of sublimation for Cu and Ag at 298 degrees K were, respectively, 68.38 and 80.0 kcal/mole. (Author)
