| abstract | PURPOSE: To easily produce respective electrodes in a large quantity by a common process by forming an ion selective film on a laminate film of a working electrode part and forming an ion permeable film on the laminate film of a reference electrode part. n CONSTITUTION: The ion sensor 1 is constituted by providing the working electrode 3, the reference electrode 4 and the common electrode 5 on the surface of an insulating substrate 2. A thin film 6 of titanium is deposited and a silver film 7 is formed in the region of the electrodes 3, 4, then silver chloride films 8 and thin films 9 of polytetrafluoroethylene are accumulated several times in order to enhance the adhesiveness between the respective electrodes and the substrate. A platinum film 13 and a gold film 14 are deposited on the thin film 6 of the electrode 5 and the contact parts 10, 11, 12. The ion selective film 19 is deposited on the electrode 3 and the ion permeable film 20 on the electrode 4. The concn. of the ions to be measured is measured if such sensor 1 is immersed in a liquid to be detected and the potential difference of the electrodes 3, 4 is measured. The electrodes 3, 4 have the laminate film of the same constitution and is produced by nearly the same process and, therefore, the mass production is facilitated. n COPYRIGHT: (C)1991,JPO&Japio |
