ALL-SOLID STATE REFERENCE ELECTRODE

摘要

All-solid state reference electrode for use in e.g. potentiometric, amperometric and voltametric measurements, comprising: a first and second resistor (102a, 102b) connected to a first and second wire (101a, 101b) respectively; a first and second conductive element (105a, 105b) externally coated with a first and second solid electrically conductive layer (106a, 106b), in which the element (105a, 105b) is connected to the idle connection of said first and second resistor (102a, 102b) or to the free end of said first and second wire (101a, 101b), respectively; and a first and second membrane (107a, 107b) surrounding said first and second solid electrically conductive layer (106a, 106b), respectively, the first membrane (107a) comprising a matrix, an anion-exchange material and optionally a lipophilic salt, and the second membrane (107b) comprising a matrix, a cation-exchange material and optionally a lipophilic salt, thus forming an anion-conducting membrane (107a) and a cation-conducting membrane (107b)
