Abstract
The invention provides a solid state reference electrode comprising: a reference element in ionic communication with a composite, the composite comprising a water-permeable polymeric matrix loaded with a solid inorganic salt comprising a reference anion; an electrode surface for contacting an analyte; and a solid ion-exchange material located between the electrode surface and the reference element, the solid ion-exchange material comprising one or more non-interfering ions, wherein in use the solid ionexchange material immobilises one or more interfering ions, when present in solution in the analyte, by exchange with the noninterfering ions.
