Coulometric analyzer
Abstract
Abstract THE INVENTION IS A CONTROLLED POTENTIAL COULOMETRIC ANALYZER USED IN MEASURING THE CONCENTRATION OF CHLORINE IN A GAS. THE ANALYZER UTILIZES WORING AND AUXILIARY ELECTRODES OF PLATINUM AND AN ELECTROLYTE OF HYDROCHLORIC ACID SOLUTION. THE CATHODE OR WORKING ELECTRODE COMPARTMENT IS CONNECTED BY LIQUID PASSAGES TO SEPARATE COMPARTMENTS CONTAINING THE AUXILIARY ELECTRODE OR ANODE AND REFERNCE ELECTRODE. WHEN THE WORKING ELECTRODE IS MAINTAINED AT A POTENTIAL OF +375 MV. WITH RESPECT TO A SATURATED CALOMEL ELECTRODE, THE CELL CURRENT IS ZERO IN THE ABSENCE OF CHLORINE. WHEN A VOLUME OF SAMPLE GAS CONTAINING CHLORINE IS INTRODUCED INTO THE GAS SPACE ABOVE THE CATHODE, THE CHLORINE DISSOLVES IN THE THIN FILM OF ELECTROLYTE, WETTING THE PLATINUM GAUZE CATHODE AND IS REDUCED AT THE CATHODE. THE INTERGRATED CURRENT OR TOATL CHARGE THAT FLOWS AS A RESULT OF THE ELECTROLYSIS IS PROPORTINAL TO THE CHLORINE REDUCED, AND SUCH CHARGE IS READ ON SUITABLE READOUT EQUIPMENT. D R A W I N G
