ELECTROCHEMICAL APPARATUS FOR CONTROLLING AND MEASURING A GAS AND ITS APPLICATION TO MONITORING LEAKS OF FLUORHYDRIC ACID

摘要

THE INVENTION RELATES TO ELECTROCHEMICAL DEVICES FOR CONTROLLING A GAS CONSTITUENT. /P P IT RELATES TO AN ELECTROCHEMICAL DEVICE IN WHICH A CATHODE 6, FORMED FOR EXAMPLE OF A WINDING OF PLATINUM WIRE, HAS A SURFACE OF CONTACT WITH THE AMBIENT ATMOSPHERE AND WITH AN ELECTROLYTE MUCH SUPERIOR THAN THAT OF AN ANODE 7. THE ELECTROLYTE USED IS A DELIQUESCENT SOLUTION OF A BROMIDE AND A BROMATE. THE PROBE IS INTENDED TO DETECT THE PRESENCE OF HYDROFLUORIC ACID. /P P APPLICATION TO THE DETECTION OF HYDROFLUORIC ACID LEAKS FROM CHEMICAL PLANTS.
