Dvs isotherm plot
Dynamic vapor 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. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces. Water vapor … See more 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 … See more Figure 1 shows a typical water sorption result from a DVS experiment for a microcrystalline cellulose sample. The kinetic data (Figure 1a) shows the change in mass and … See more • Hygroscopy • Moisture sorption isotherm • Water content See more DVS measurement has applications over a wide range of industries. Both equilibrium vapor sorption isotherms and vapor sorption kinetic results can yield vital information for materials ranging from pharmaceuticals to fuel cells.
