Liquid junction structure for plastic electrochemical electrodes
Abstract
Abstract LIQUID JUNCTION STRUCTURES FOR PLASTIC ELECTROCHEMICAL ELECTRODES AND METHODS OF MANUFACTURING THE SAME ARE DISCLOSED. ONE EMBODIMENT COMPRISES A TUBE OF PLASTIC HAVING AN OPEN END WITH AN ION SENSITIVE STRUCTURE MOUNTED THEREIN. A SMALL LONGITUDINAL CHANNEL IS FORMED IN THE TUBE WHICH EXTENDS FROM THE OPEN END PAST THE MEMBRANE TO OPEN INTO THE INTERIOR OF THE TUBE. A BUNDLE OF FIBERS IS POSITIONED IN THE CHANNEL COVERED BY A SLEEVE OF INJECTION MOLDED PLASTIC FOR COMPACTING AND RESTRAINING THE FIBERS. THE EMBODIMENT ENABLES A PLANAR SENSING SURFACE FOR A PLASTIC COMBINATION ELECTRODE. ANOTHER EMBODIMENT COMPRISES A TUBE HVING AN EXTENDED LIP PORTION SURROUNDING AN OPENING AND A SHRINK TUBE SURROUNDING THE LIP PORTION. A BUNDLE OF FIBERS IS POSITIONED IN THE OPENING; THEREAFTER THE LIP PORTION AND THE SHRINK TUBE ARE HEATED TO MELT AND CONTRACT THE LIP PORTION AND THE SHRINK TUBE RESPECTIVELY ABOUT THE FIBERS.
