PROCESS FOR DETERMINING PRESENCE AND CONCENTRATION OF A COMPONENT OF A FLUID MIXTURE WHICH COMPRISES DIVIDING THE MIXTURE INTO TWO STREAMS OF EQUAL FLOW, PASSING ONE OF THE STREAMS IN CONTACT WITH AN ACIDIC SOLUTION CONTAINING AN AGENT SELECTIVELY REACTIVE WITH THE COMPONENT TO YIELD A SOLUTION OF LOWERED IONIC MOBILITY, PASSING THE OTHER STREAM IN CONTACT WITH AN ACIDIC SOLUTION CONTAINING AN INERT SALT IN AMOUNT TO EQUALIZE ITS ELECTRICAL CONDUCTIVITY WITH THAT OF THE FIRST MENTIONED SOLUTION PRIOR TO THE PASSAGE OF THE STREAM, AND MEASURING THE DIFFERENCE IN CONDUCTIVITY OF THE TWO SOLUTIONS DURING THE PASSING OF THE STREAMS.
