Abstract
A combination electrode includes a working electrode, a reference electrode, a hydrogel diaphragm, an outer tube and an inner tube. The working electrode is disposed in the inner tube. The reference electrode is disposed in a reference chamber formed between the inner tube and the outer tube. The hydrogel diaphragm seals the opening between an end of the outer tube and the inner tube when the hydrogel swells upon coming in contact with a first electrically conductive fluid that is introduced into the reference chamber. The diaphragm is coupled to the reference electrode in an electrically conductive manner through the first electrically conductive fluid, which contacts both the reference electrode and the diaphragm. The inner tube is closed by a glass membrane that is coupled to the working electrode in an electrically conductive manner through a second electrically conductive fluid that contacts both the glass membrane and the working electrode.
