Jill M Geist, Thomas G Schapira: Membrane anchor for ion-selective electrodes. Abbott Laboratories, Dennis K Shelton, Martin L Katz, September 20, 1988: US04772377 (8 worldwide citation)

A membrane anchor for an ion-selective electrode may be formed by intersolubilizing an ion-selective membrane lying above a sensing pad with a region of thermoplastic material laterally disposed around the membrane. A first layer of electrically insulating thermoset material lies beneath the thermop ...
