Abstract (EN): 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 bene¿cial for a PDMS based sensor when analyzing oxygen/nitrogen gas mixtures. © 2006 Elsevier B.V. All rights reserved.
