Abstract 1. A METHOD OF POTENTIOMETRIC ANALYSIS OF A SERIES OF LIQUID SAMPLES FOR A CONSTITUENT OF INTEREST UTILIZING A REFERENCE ELECTRODE AND A SENSING ELECTRODE HAVING AN ION-SELECTIVE SURFACE PORTION, SAID REFERENCE ELECTRODE AND SAID ION-SELECTION SURFACE PORTION OF SAID SENSING ELECTRODE DEFINING, IN PART, A FLOW-THRU CONDUIT, COMPRISING THE STEPS OF: FLOWING THE LIQUID SAMPLES SEQUENTIALLY IN A STREAM ALONG SAID CONDUIT; INTRODUCING GAS TO SEGMENT THE STREAM OF SAMPLE TO FORM GAS SEGMENTS INTERMEDIATE EACH SAMPLE AND ITS NEIGHBORING SAMPLES SO THAT EACH SAMPLE COMPRISES A LIQUID SEGMENT; PASSING SAID FLOWING STREAM ALONG SAID CONDUIT TO CONTACT SAID REFERENCE ELECTRODE AND SAID ION-SELECTIVE SURFACE PORTION OF SAID SENSING ELECTRODE WITH SAID SAMPLE LIQUID AND GAS SEGMENTS IN SAID FLOWING STREAM; LOCATING SAID ELECTRODES WITH RESPECT TO EACH OTHER SUCH THAT EACH SAMPLE LIQUID SEGMENT IN SAID STREAM BRIDGES SAID REFERENCE ELECTRODE AND SAID ION-SELECTIVE SURFACE PORTION OF SAID SENSING ELECTRODE; AND MEASURING THE ELECTRICAL POTENTIAL ACROSS SAID ELECTRODES FOR ANALYSIS OF SAID LIQUID SAMPLE SEGMENTS.
