Abstract
In this paper, we report on a thin film sensor for the detection of carbon dioxide dissolved in liquids with the attention focused on its use for clin ical blood gas analysis. Carbon dioxide from the analyte penetrates into a hydrogel electrolyte through a gas permeable membrane and is chemisorbed on a rhodium working electrode. The concentration of CO2 collected by this wa y is determined by an amperometric measurement technique based on the inver se voltammetry. (C) 2001 Elsevier Science B.V. All rights reserved.
