ABSTRACT:
An ion selective electrode includes a conductive electrode body which is supported by an insulating substrate. A convex dome-shaped membrane containing an electroactive species is deposited over and is directly in contact with the electrode body and a surface of the substrate surrounding the electrode body. The membrane has its greatest height above the electrode body and slopes down to meet the surface of the substrate. A moat formed in the insulating substrate surrounds the space from the electrode body to define the outer boundary of the dome-shaped member.
