    Abstract: A pH sensor has an electrode assembly with an electrode with a core of an electrochemically inert insulating or semiconductive material, and is coated with an electrically conductive, electrochemically sensitive coating. The preferred core is insulating and made of alumina, with a thin coating of iridium oxide deposited over at least a portion of the outer surface of the core. The coating is carried to a region remote from the sensing surface and is used for making electrically conductive connections that lead to remote circuitry. The core is made in a form that can be supported and held in an insulating, electrochemically inert, deformable material that is sealed around the outer surface of the coating on the core to prevent leakage of chemicals being sensed. An outer housing also permits sealing quite easily into access ports on which the sensor housing is mounted.

    Abstract: The present invention includes an ion diffusion junction in an electrochemical cell. The junction includes a polymer matrix that is impermeable to the sample solution. A plurality of inclusions are disposed within the junction matrix and oriented to form continuous hydrolytic pathways extending between the sample solution (34) and the reference electrolyte (18) such that ion diffusion occurs along the hydrolytic pathways.
