Abstract
A reference electrode with an in-situ modified porous diaphragm has at least one housing (), a first conductor element (), a modifying electrolyte which is capable of free-flow movement and is contained in the housing (), and a porous diaphragm () which establishes a liquid connection between the modifying electrolyte and a measurement medium (). The modifying electrolyte seeps out through the porous diaphragm during operation. The modifying electrolyte has a first component and a surface-modifying component which modifies the surface of the porous diaphragm () in situ during the passage of the modifying electrolyte. A method for modifying the porous diaphragm in situ is presented.
