摘要:
A device is described which is useful for the determination of vapor density for condensable vapors in the temperature range from the melting point to the critical temperature and in the pressure range from the vapor pressure at the melting point to the critical pressure. The method requires only a one‐ to two‐gram sample for one entire series of measurements over the complete temperature and pressure range, and the sample is recoverable. Surface adsorption and liquid densities can be determined by parallel systems and at the same time. Precision is limited only by the measurement and control of thermostats and by the accuracy of direct weighing.

摘要:
An apparatus designed to determine the thickness of films deposited on metal slides is described. It is based on the measurement of the change that takes place in ellipticity of the light reflected after a slide has been coated with the film under investigation. The apparatus is capable of measuring a film thickness within ±0.3A, a sensitivity at least ten times greater than that obtained with the method based on light interference.
