Procedure for the construction of all-solid-state PVC membrane electrodes

Abstract

A procedure for the construction of all-solid-state PVC membrane electrodes, which consists in depositing the PVC membrane on a conductive epoxy support mounted in a Perspex body, has been developed. The technique was tested for potassium-, nitrate- and calcium-selective electrodes with Corning 477317, Orion 92-07-02 and Orion 92-20-02 commercial sensors, respectively, whose response characteristics are presented. The advantages and shortcomings of the new type of selective device are discussed.
