  • Reference electrode with ion barrier for electrochemical measuring systems
    Patent number: 5470453
    Abstract: A reference electrode (2) which features an ion barrier (20) based on the redox principle and which is fashioned as an independent unit or as part of a combination electrode, for instance a single-rod measuring chain. Metal ions to be blocked and contained in the reference electrolyte (24) and the material forming the ion barrier (20) together form a redox system. The ion barrier (20) is preferably a reduction agent which reduces the metal ions to the respective metal, and its properties are such that it will not cause contamination of the diaphragm (6) in oxidized state.
