The laboratory is specializes in the study of the transport of gases, vapors and their mixtures through flat polymer membranes. The self-developed permeameters are used to determine the permeability and diffusion coefficients, respectively. The diffusion coefficients of gases and vapors in polymers are evaluated from the (gas or vapor) sorption kinetics. Sorption experiments are performed gravimetrically via Mc Bain spiral balances. These balances are also used to determine the sorption isotherms and the sorption coefficients of gases and vapors in polymers.
