Vapor Pressure Measurement

RSS
Vapour pressure measurements can reveal the evaporation rate of a liquid or sublimation rate of a solid. More specifically, vapor pressure analyzers reveal the pressure applied by a vapor in thermodynamic equilibrium with its solid or liquid phase at a particular temperature in a closed system. Samples with high vapor pressures at normal temperatures are regarded as having unstable vapor pressures. Vapour pressure assessments of unstable liquids, like petroleum and gasoline, are crucial from both a safety and quality perspective. Vapour pressure analyzers can identify the effects of additives, provide performance indications, and gauge a liquid’s tendency to vapor lock under specified conditions.
