Dynamic Vapour Sorption - DVS

Dynamic Vapor Sorption (DVS) analyzers, employ a gravimetric technique in order to measure the mass of a sample as it responds to changes in the temperature or humidity of the environment surrounding it. A typical DVS experiment involves the exposure of a sample to an environment where the temperature is typically constant, however, humidity in this area is known to vary. In this type of analyzer, the mass of a sample must reach gravimetric equilibrium before being exposed to any other level of humidity. The change in the mass of a sample is then recorded at each level of humidity.
