Abstract
1424029 Ion selective electrode CONTROL DATA CORP 24 Oct 1973 [15 Jan 1973 (3)] 49585/73 Heading G1N An ion selective electrode comprises a solid imporous membrane of an intimate mixture of cuprous sulphide or gold and a compound selective to ions in solution. The membrane preferably comprises 5-95 mole % of cuprous sulphide or 1-50 mole % gold and one or more of silver chloride, bromide, iodide, sulphide, cyanide or thiocyanate, copper sulphide, cadmium sulphide or lead sulphide and contains no free silver, cadmium, lead or copper. It is preferably formed by compression moulding. The electrode may comprise a tube of PTFE, epoxy resin, PVC, gloss or ABS terpolymer, with its lower end plugged by the membrane. It contains a reference electrolyte and an electrode of platinum or silver wire (with optional coating of AgCl) extends into the solution through a cap which seals the tube. In a preferred embodiment as shown, wire electrode 16 is sealed through cap 14 and passes into the reference electrolyte 20 via a seal 22. The membrane 24 is held between two parts of barrier 28 which screws into the main tube 12 and the two parts being joined by plastics material passing through holes in the membrane. The internal electrolyte may be 0À1M aqueous KCl saturated with AgCl. The electrodes have a fairly low internal resistance which simplifies measurement.
