Abstract
An ion-sensitive electrochemical sensor comprises an electrode body having an ion-sensitive polymeric membrane coated thereon. The membrane comprises a water-insoluble copolymer having ion exchange sites and has a glass transition temperature greater than about 80.degree. C. The sensor is used to determine ion concentration by contacting it with a test solution and determining the ion concentration as a function of the potential of the electrode.
