Alkalinity measurement of an aqueous sample

A measurement device for compensating for interferants in measurement of alkalinity in a reagent-less system, comprising:

• at least one chamber;
• one or more series of electrodes at least partially disposed within one of the at least one chamber;
• a processor;
• and
• a memory device that stores instructions executable by the processor to:
• introduce an aqueous sample into a measurement device comprising one or more series of electrodes;
• apply an electrical signal to the aqueous sample using the one or more series of electrodes, wherein the electrical signal is selected from the group consisting of:
• current and voltage;
• identify, during application of the electrical signal, that the electrical signal reaches an oxidation threshold and measuring, prior to reaching the oxidation threshold, a first electrical response to the electrical signal, the first electrical response attributable to interferants in the aqueous sample;
• identify, during application of the electrical signal, that the electrical signal reaches an endpoint and measuring, from the oxidation threshold to the endpoint, a second electrical response to the electrical signal;
• and
• measure an alkalinity of the aqueous sample based upon a difference between the first electrical response and the second electrical response.
