ABSTRACT:
An ion sensitive electrode device and method of its use in analytical and clinical chemistry are provided for measuring the concentration of an ionizable analyte contained in an aqueous medium. The device with external circuit means includes an electrode pair adapted to be placed in electrochemical contact with the medium. The electrode pair includes a polarographically active base metal/metal oxide working electrode and a reference electrode. The external circuit means is adapted to measure the voltage generated by the electrode pair in open circuit and to measure the closed circuit current flow at a preselected impedance and including means for comparing said voltage and current flow values with predetermined reference standards to provide a third value representative of said analyte concentration.
