Abstract
A new concentration sensor for binary gas mixtures based on the permselectivity of polymeric membranes has been recently developed. The sensor responds to temperature changes. This work describes a simple way to compensate most of the temperature effect on the sensor's response. Different membrane materials and gas mixtures were tested. The present approach proved to be especially beneficial for a PDMS based sensor when analyzing oxygen/nitrogen gas mixtures.
