Electrolytic oxygen analysis

Claim 1

AN APPARATUS FOR THE COURLOMETRIC ANALYSIS OF OXYGEN IN A FLOWING GAS STREAM CONSISTING IN COMBINATION OF AN ELECRTOLYTIC CELL PROVIDED WITH A POROUS CATHODE ELEMENT SELECTED FROM THE GROUP CONSISTING OF SILVER AND COPPER AND AN ANODE ELEMENT BEING SUNSTANTIALLY INERT CHEMIELECTROLYTE SOLUTION NON-REDUCIBLE AT THE ANALYSIS POTENTIAL, SAID ANODE ELEMENT BEING SUBSTANTIALLY INERT CHEMICALLY WITH RESPECT TO SAID ELECTROLYTE SOLUTION, MEANS MAINTAINING SAID CATHODE ELEMENT AT A POTENTIAL OF BETWEEN ABOUT -0.1 V. AND - 1.7 V. WITH RESPECT TO SAID ELECTROLYTE SOLUTION, A GAS SAMPLE SUPPLYING CONDUIT OPENING AGJACENT SAID CATHODE ELEMENT TO DIRECT SAID FLOWING GAS STREAM THROUGH SAID POROUS CATHODE ELEMENT INTO INTIMATE CONTACT THEREWITH AND WITH SID ELECTROLYTE SOLUTION TO THEREBY EFFECT COMPLETE ELECTROLYTIC REDUCTION OF THE OXYGEN IN SAID FLOWING GAS STREAM. MEAN IMPOSING A D-C. ELECTRICAL BIAS BETWEEN SAID CATHODE AND ANODE ELEMENTS IN OPPOSITION TO THE VOLTAGE GENERAL BY SAID ELECTROLYTIC CELL AND IN AN AMOUNT REDUCING ELECTRICAL BACKGROUND INTERFERENCE EXISTING IN SAID CELL DURING SAID ANALYSIS, AND MEANS FOR DETERMINING ATHE CONTENT OF OXYGEN IN SAID FLOWING GAS STREAM AS A FUNTION OF THE ELECTRIC CURRENT FLOW BETWEEN SID CATHODE ELEMENT AND SAID ANODE ELEMENT.
