Automatic Microscale Vapor Pressure Analyzer
Automatic Microscale Vapor Pressure Analyzer
Description
The design of the K24870 Microscale Vapor Pressure Analyzer is based on the Triple-Expansion Principal for vapor pressure determination. The sample of known volume is injected into a temperature controlled measuring chamber with a piston in it, which is then sealed. The volume of the sample is expanded by X times in three steps.
The total pressure after every expansion step is measured and the dissolved partial pressure of the air and dissolved partial pressure of air in the sample are calculated. The temperature is then raised to a certain value and the total pressure is measured at the temperature. By taking the difference of the total pressure after final expansion and the partial pressure from dissolved air, the vapor pressure of the sample is calculated.
