  • Method of determining ion activity using coated ion selective electrodes
    Patent number: 4115209
    Abstract: The potentiometric responses caused by ion activity changes in solution are measured with an electrode formed by coating an ion exchange material which is molecularly dispersed throughout an insoluble film-forming polymeric matrix directly onto a conductive substrate such that an oxidation-reduction mechanism is not operative in the response of said electrode to the activity of ions in said solution.
