Abstract: An integrated reference electrode for use in an electrochemical measurement system, comprising: a reference electrode in combination with a hygroscopic hydrogel electrolyte impregnated and contained in a porous framework, wherein the hygroscopic hydrogel electrolyte is adapted to contact the reference electrode when in a hydrated state. Also, an ion selective membrane with an aromatic epoxy polymer made from one or more monomers having at least one epoxide group, and a chloride salt or a silver - silver chloride physically trapped in the aromatic epoxy polymer. On contact with water the aromatic epoxy polymer forms a network of channels for ion exchange. The membrane may be used between an electrolyte and an external fluid environment; or the membrane may be coated upon the surface of a reference electrode.
