Abstract
It was the objective of this research project to find reliable methods which allow the prediction of steady state oxygen transmission from transient state measurements. Therefore, two models were tested, one using nonlinear regression analysis in combination with an equation describing the transient state, the other using a partial pressure pulse instead of a constant change in partial pressure. The applicability of both methods in combination with a standard oxygen transmission rate test equipment has been checked for different monolayers and multilayers. With the help of these methods the test procedure can be shortened. More detailed information of the permeation process is given by the fundamental diffusion and solubility coefficients which are calculated with the methods. Both models are valid only for ideal diffusion. Some factors are described that lead to deviations from ideal conditions and influence the results.
