DVS Dynamic Vapour Sorption Analysis
- automated analysis of water sorption properties of materials
provides information on hydration, diffusion and permeability, sorption/desorption isotherms, kinetics of water
uptake, activation energies and heats of sorption and desorption, moisture content. Applications include pharmaceutical
powders and complexes, films, paper, food, fibres

Organic DVS Applications
- include hydrophbic pharmaceutical powders and formulations, where water sorption is poor or extremely slow,
or where crystallisation is carried out from organic solvents; in these cases water sorption is not always able
to measure the full extent of amorphous material
