Patent ID: 10724984

Abstract:
An embodiment provides a method for oxidizing organic carbon, including: introducing, in a reaction chamber of a total organic carbon analyzer, a fluid sample comprising organic 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; applying, using a generator, 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, in the reaction chamber, at least one acid reagent comprising a metallic catalyst, prior to or substantially simultaneously during the application of the positive potential to the SP3 substituted carbon electrode, that converts the carbonate and the partially oxidized species to carbon dioxide; and detecting, using at least one detector, the carbon dioxide produced by the oxidation. Other aspects are described and claimed.
