Method and apparatus for electroextraction

Abstract

Abstract A METHOD OF ELECTROEXTRACTION WHICH COMPRISES THE STEPS OF PLACING A SAMPLE INTO A SAMPLE CHAMBER, SIMULTANEOULY FILLING SAID CHAMBER AND TWO ELECTRODE VESSELS WITH A CARRIER SOLUTION, APPLYING A VOLTAGE BETWEEN THE ELECTRODES IN SUCH A MANNER THAT THE TEST COMPONENT FLOWS THROUGH A MULTISTAGE SEPARATION CHAMBER, AND SUPPLYING A CARRIER SOLUTION INTO THE MULTISTAGE SEPARATION CHAMBER TO EXTRACT THE TEST COMPONENT FROM THE SAMPLE CHAMBER THROUGH A DIALYSIS MEMBRANE INTO THE MULTISTAGE SEPARATION CHAMBER, THEN TO AN OULET. THE ELECTROEXTRACTION APPARATUS UTILIZED IN THIS PROCESS COMPRISES A D.C. POWER SUPPLY, POSITIVE AND NEGATIVE ELECTRODES CONNECTED TO THE POWER SUPPLY, TWO ELECTRODE VESSELS EACH CONTAINING AN ELECTRODE, A SAMPLE CHAMBER ADJACENT TO ONE OF THE ELECTRODE VESSELS AND SEPARATED THEREFROM BY A DIALYSIS MEMBRANE, A MULTISTAGE SEPARATION CHAMBER DISPOSED ADJACENT TO THE SMAPLE CHAMBER AND BETWEEN THE SAMPLE CHAMBER AND THE OTHER ELECTRODE VESSEL, EACH STAGE BEING SEPARATED FROM THE ADJACENT STAGE BY DIALYSIS MEMBRANES WITH A PORT PROVIDED IN THE MEMBRANES BETWEEN EACH STAGE WITH THE MULTISTAGE SEPARATION CHAMBER BEING SEPARATED FROM THE SAMPLE CHAMBER ON THE ONE SIDE AND THE OTHER ELECTRODE VESSEL ON THE OTHER SIDE BY DIALYSIS MEMBRANES, A SOURCE OF CARRIER SOLUTION, A CONSTANT FLOW PUMP FOR FEEDING THE CARRIER SOLUTION INTO THE MULTISTAGE SEPARATION CHAMBER, AND AN OUTLET FROM THE MULTISTAGE SEPARATION CHAMBER.
