How is the permeability of polymer membrane materials measured? Detection can be carried out using a Dynamic Vapor Sorption Instrument (DVS Intrinsic): Studying the diffusion and permeability of molecules in polymers and packaging materials is key to understanding and optimizing their properties. The DVS instrument can be used to study this phenomenon with a wide variety of probe molecules, including water, organic solvents, and gases, depending on the SMS instrument being used. The SMS instrument is an ideal choice for obtaining kinetic and equilibrium information on molecular diffusion and permeation of numerous materials. In addition, it can also detect the following properties of polymer materials: 1) solvent absorption and swelling, 2) drying, 3) glass transition temperature, 4) sealing performance
