The main application of DVS is to measure water sorption isotherms. In general, a vapor sorption isotherm shows the equilibrium amount of vapor sorbed as a function of steady state relative vapor pressure at a constant temperature. For water sorption isotherms, water relative vapor pressure is more commonly expressed as relative humidity. In a DVS experiment this is accomplished by exposing a sample to a series of step changes in relative humidity and monitoring the mass chan… WebThe BELSORP-mini-X sorption analyser is commonly used to measure physisorption isotherms, which are used for BET surface area analysis, as well as for porosity determination. We offer several instruments which are optimised for measuring surface areas by gas sorption.
