Vapor Pressure of Pure Component

Gas effusion-method

Temperature range:        20 °C - 250 °C
Pressure range:               10-5-103 Pa

An inert gas flow is directed through the component located in the apparatus. The gas flow is saturated with the component to be measured. The vapor pressure is determined from the mass of component transferred from the sample. The measurement time is long for substances with low vapor pressure and the component must be thermally stable at the measurement temperature.
