A method for deriving an alkalinity measurement, comprising: introducing, in a reaction chamber of an analyzer, a fluid sample comprising inorganic carbon, wherein the reaction chamber includes an electrochemical cell and wherein the electrochemical cell comprises an SP3 substituted solid carbon electrode doped with a conductivity elevating composition; measuring, using a phosphate analyzer of the analyzer, a phosphate amount of the fluid sample using a colorimetric reagent; measuring, using a pH sensor of the analyzer, a pH of the fluid sample, wherein the pH of the fluid sample correlates to a hydroxide amount of the fluid sample; introducing an acid reagent to convert the inorganic carbon to carbon dioxide, wherein the inorganic carbon comprises carbonate and bicarbonate; applying, using a generator of the analyzer, a positive potential to the SP3 substituted carbon electrode, the positive potential being sufficient to oxidize organics in the fluid sample to produce carbonate and partially oxidized organics; introducing, prior to or substantially simultaneously during the application of the positive potential to the SP3 substituted carbon electrode and in the reaction chamber, at least one acid reagent comprising a metallic catalyst that converts the carbonate and the partially oxidized species to carbon dioxide; determining total organic carbon by detecting, using at least one detector of the analyzer, an amount of carbon dioxide produced by the oxidation; and determining a derived alkalinity based upon the phosphate amount, the hydroxide amount, and the amount of carbon dioxide generated from the inorganic carbon. introducing, in a reaction chamber of an analyzer, a fluid sample comprising inorganic carbon, wherein the reaction chamber includes an electrochemical cell and wherein the electrochemical cell comprises an SP3 substituted solid carbon electrode doped with a conductivity elevating composition; measuring, using a phosphate analyzer of the analyzer, a phosphate amount of the fluid sample using a colorimetric reagent; measuring, using a pH sensor of the analyzer, a pH of the fluid sample, wherein the pH of the fluid sample correlates to a hydroxide amount of the fluid sample; introducing an acid reagent to convert the inorganic carbon to carbon dioxide, wherein the inorganic carbon comprises carbonate and bicarbonate; applying, using a generator of the analyzer, a positive potential to the SP3 substituted carbon electrode, the positive potential being sufficient to oxidize organics in the fluid sample to produce carbonate and partially oxidized organics; introducing, prior to or substantially simultaneously during the application of the positive potential to the SP3 substituted carbon electrode and in the reaction chamber, at least one acid reagent comprising a metallic catalyst that converts the carbonate and the partially oxidized species to carbon dioxide; determining total organic carbon by detecting, using at least one detector of the analyzer, an amount of carbon dioxide produced by the oxidation; and determining a derived alkalinity based upon the phosphate amount, the hydroxide amount, and the amount of carbon dioxide generated from the inorganic carbon.
