A new method to estimate permeation coefficients for small sized polymer samples is introduced. It uses a mass spectrometer to measure the partial pressure of gas permeating from an enclosed volume of gas as a function of time. In agreement with predictions from a simple model the partial pressure v
Steady-state permeation rates for pure COz and CH4 and the binary mixture through homogeneous dense polysulfone and polycarbonate membranes have been measured at 40Β°C and upstream pressures up to 26 atm. The pressure dependence of the mean permeability coefficients for COz and CH, for all of the sys
