Apparatus for measuring liquid vapor adsorption and desorption characteristics of a sample |
摘要 |
In order to measure the adsorption and desorption characteristics of water vapor by a porous or powdery sample, the sample is placed in an automated device which measures the difference between an equilibrium pressure and a sample pressure for various values of sample pressures, during both adsorption and desorption. A programmable computer calculates the amount of water vapor adsorption and desorption based upon the equilibrium pressure and can be used to control a printer for plotting the resulting data.
