ABSTRACT:
A reference electrode in the form of a conductor, an ion sensitive field effect transistor or a liquid-membrane electrode kit, coated with a membrane of a high polymer which contains an arsonium borate. Since the reference electrode dispenses with a liquid junction region which has been required of a conventional liquid-junction type reference electrode, it has the following features. (A) It does not matter if the reference electrode is allowed to dry during storage. (B) The test solution is not contaminated by the internal solution. (C) Reduction in size of the reference electrode can be easily attained.
