Abstract
An electroanalytical electrode assembly includes an electrically conductive working electrode having a body of electrolyte material thereupon and separated from the analytical environment by a hydrophobic membrane. The membrane has an electrical conductivity greater than the electrical conductivity of the remainder of the measuring circuit and is selectably permeable for a preselected and ionic species, so as to provide a stable membrane potential. Use of an assembly of this type allows for placement of a reference electrode external of the membrane.
