text: This apparatus, based on a capacitance diaphragm gage, is capable of measuring vapor pressures of either crystalline or liquid samples in the pressure range (0.4 to 133) Pa and in the temperature range (243 to 413) K. To test the performance of the new apparatus, it was decided to measure the vapor pressures of four compounds recommended as reference materials (naphthalene,benzoic acid,benzophenoneand ferrocene) although the vapor pressure data for some of these compounds are not yet accurately
