Photoacoustic detectors prove to be excellent instruments for experimental assessing gas permeability parameters of rubbers and polymers because of the detector’s sensitivity and large dynamic range. Our research group conducts developments with the aim of improving the speed, the effectiveness and the accuracy of these experimental methods.
