WebDynamic vapour sorption (DVS) is a gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample, such as a dry powder absorbing water. … 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… greenwood branch library hours https://thaxtedelectricalservices.com
