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.
