Method of determining the concentration of a chemical constituent of a fluid

Claim 1

THE METHOD OF DETERMINING THE CONCENTRATIONOF A HALOGEN DISSOLVED IN A FLUID, COMPRISING THE STEPS OF CONTINUOUSLY SUBJECTING A PORTION OF THE FLUID FLOWING AS A STREAM AT A CONSTANT VELOCITY TO TREATMENT FOR REMOVING SAID HALOGEN AS SUCH THEREFROM, THEREAFTER CONTINUOUSLY ADDING TO SAID STREAM AT A DETERMINABLE VARIABLE RATE A CHEMICAL AGENT TO ESTABLISH A KNOWN CONCENTRATION OF SAID CHEMICAL AGENT THEREIN, SAID CHEMICAL AGENT BEING DIFFERENT FROM SAID HALOGEN BUT ONE WHICH WILL REACT QUALITATIVELY THE SAME AS SAID HALOGEN AND QUANTITATIVELY PROPORTIONAL THEREWITH WHEN SUBJECTED TO A PREDETERMINED ANALYTICAL TEST, SAID CHEMICAL AGENT FURTHER BEING ONE CAPABLE OF BEING ADDED CONTINUOUSLY WITH GREATER PRECISION AND RELIABILITY THAN SAID HALOGEN, SAID CHEMICAL AGENT FURTHER BEING A COMPOUND HAVING A NORMAL OXIDATION POTENTIAL IN THE RANGE BETWEEN ABOUT THAT OF IODINE AND ABOUT THAT OF PERMANGANATE, AND CONTINUOUSLY COMPARING SAID STREAM TO WHICH SAID CHEMICAL AGENT IS ADDED WITH A SIMILAR STREAM OF THE UNTREATED FLUID BY SAID PREDETERMINED ANALYTICAL TEST TO DETERMINE THE RELATIVE EQUIVALENT CONCENTRATIONS OF SAID HALOGEN AND SAID CHEMICAL AGENT, THE RESULTS OF SUCH COMPARISON, TAKING INTO ACCOUNT THE DETERMINED RATE OF ADDITION OF SAID AGENT AND THE EQUIVALENT VALUES OF SAID AGENT AND SAID HALOGEN AS THEY AFFECT SAID ANALYTICAL TEST, BEING INDICATIVE OF THE CONCENTRATION OF SAID HALOGEN.

Claim 2

THE METHOD OF DETERMINING THE CONCENTRATIONOF A HALOGEN DISSOLVED IN A FLUID, COMPRISING THE STEPS OF CONTINUOUSLY SUBJECTING A PORTION OF THE FLUID FLOWING AS A STREAM AT A CONSTANT VELOCITY TO TREATMENT FOR REMOVING SAID HALOGEN AS SUCH THEREFROM, THEREAFTER CONTINUOUSLY ADDING TO SAID STREAM AT A DETERMINABLE VARIABLE RATE A CHEMICAL AGENT TO ESTABLISH A KNOWN CONCENTRATION OF SAID CHEMICAL AGENT THEREIN, SAID CHEMICAL AGENT BEING DIFFERENT FROM SAID HALOGEN BUT ONE WHICH WILL REACT QUALITATIVELY THE SAME AS SAID HALOGEN AND QUANTITATIVELY PROPORTIONAL THEREWITH WHEN SUBJECTED TO A PREDETERMINED ANALYTICAL TEST, SAID CHEMICAL AGENT FURTHER BEING ONE CAPABLE OF BEING ADDED CONTINUOUSLY WITH GREATER PRECISION AND RELIABILITY THAN SAID HALOGEN, SAID CHEMICAL AGENT FURTHER BEING A COMPOUND HAVING A NORMAL OXIDATION POTENTIAL IN THE RANGE BETWEEN ABOUT THAT OF IODINE AND ABOUT THAT OF PERMANGANATE, AND CONTINUOUSLY COMPARING SAID STREAM TO WHICH SAID CHEMICAL AGENT IS ADDED WITH A SIMILAR STREAM OF THE UNTREATED FLUID BY SAID PREDETERMINED ANALYTICAL TEST TO DETERMINE THE RELATIVE EQUIVALENT CONCENTRATIONS OF SAID HALOGEN AND SAID CHEMICAL AGENT, THE RESULTS OF SUCH COMPARISON, TAKING INTO ACCOUNT THE DETERMINED RATE OF ADDITION OF SAID AGENT AND THE EQUIVALENT VALUES OF SAID AGENT AND SAID HALOGEN AS THEY AFFECT SAID ANALYTICAL TEST, BEING INDICATIVE OF THE CONCENTRATION OF SAID HALOGEN.
