About This Product

Vapor Pressure Analyzer (VPR) uses the Knudsen spillover method to measure the vapor pressure of solids, liquids, and oils. Vapor pressure is an important material physical property that defines the amount of vapor-phase material present in equilibrium with the original material. All substances enter the gas phase by sublimation (solid-gas) or evaporation (liquid-gas). The vapor pressure of a material at thermodynamic equilibrium is a fundamental property of the material and its only function of temperature.

■Knudsen methodThe Knudsen efflux method is a dynamic gravimetric technique based on the rate at which vapor molecules escape into a vacuum at a known temperature through an orifice of known dimensions in a Knudsen cell. The rate of mass loss through the orifice is measured by Surface Measurement Systems' Ultrabalance in the VPA system. Sample masses from 1 to 100 mg can typically be studied at temperatures ranging from 20 to 400 °C.
