Vapor phase detectors
Abstract
Abstract THE CHANGE IN POTENIAL DIFFERENCE, RESISTANCE OR CURRENT FLOW BETWEEN ELECTRODES IN AN ELECTROLYTIC CELL IS UTILIZED TO DETECT PRESSURE CHANGE, ABSOLUTE HYDROGEN PRESSURE AND PRESSURE OF OTHER GASES PRESENT IN HYDROGEN CARRIER GAS, PARTICULARLY THOSE WHICH ARE REACTIVE WITH THE ELECTRODES. AT LEAST ONE OF THE ELETRODES IS FORMED OF A MATERIAL SELECTIVELY PERMEABLE TO HYDROGEN, PREFERABLY COMPRISING PALLADIUM. THE CELL MAY BE SIMULTANEOUSLY UTILIZED FOR SEPARATION AND REGENERATION OF HYDROGEN CARRIER GAS AND MAY BE CONVENIENTLY INTERGRATED AND COMBINED WITH A GAS CHROMATOGRAPHIC COLUMN ON A SMALL SIZE CHIP CONTAINING RECESSES FOR THE CELL AND COLUMN COMPONENTS FORMED BY CONVENTIONAL ETCHINGMASKING TECHNIQUES.
