Dynamic Vapor Sorption & IGC SEA
Dynamic Vapor Sorption, DVS from Surface Measurement Systems is an analysis instrument for measurement of sorption and desorption proporties of a sample.
It is a gravimetric technic, a quantitative measurement of changes in mass, measuring how quick and how much a given solvent ( water or organic) is absorbed or adsorbed in a sample. This is done by measuring a change in the mass of the sample at different concentrations of relative humidity, measured as function of time.
iGC-SEA from Surface Measurement Systems is a Surface Energy Analyzer, using gas phase sorption technic to characterizing the physical- chemical surface properties of a product, such as powder, fibers, film, particles and semi-solid products.
DVS and iGC-SEA are used to measure drying/dehydration, amorphous content, Glass Transition temperature, diffusion/permeability, heat of sorption, polymer-solvent diffusion, porosity, surface area BET, surface energy, vapor pressure, density, Aw and much more. They are used in industries of ie. Food , Pharma and Plastic, in chemical industry, construction industry as well as in research.
