Abstract:
An embodiment provides a method for determining the alkalinity of an aqueous sample using an alkalinity sensor, including: monitoring the pH of an aqueous sample using a pH sensor in a sample cell, the pH sensor including a pH sensor electrode made of boron-doped diamond; generating hydronium ions, using a hydronium generator, in the aqueous sample in the sample cell, the hydronium generator including a hydronium-generating electrode; changing the pH of the aqueous sample by causing the hydronium generator to generate an amount of hydronium ions in the aqueous sample; quantifying and converting a current or charge to the number of hydronium ions produced to an end point of the electrochemical titration, the end point correlating to the alkalinity of a sample; and analyzing the alkalinity of the aqueous sample based on the generated amount of hydronium ions and the resulting change in pH monitored by the pH sensor.

Claim (Index 20):
A product, comprising:\n a storage device having code stored therewith, the code being executable by the processing and comprising: code that generates, at a bipotentiostat, a pH signal indicative of the pH of the aqueous sample and a hydronium generation signal indicative of an amount of hydronium generated in the aqueous sample as a result of electrolysis of water at a hydronium-generating electrode; code that controls the amount of hydronium ions generated in the aqueous sample; the bipotentiostat further comprising:\n a) a pH sensing electrode wired as a first bipotentiostat working electrode, the pH sensing electrode made of boron-doped diamond; \n b) the hydronium-generating electrode wired as a second bipotentiostat working electrode, the hydronium-generating electrode made of boron-doped diamond; \n c) a bipotentiostat reference electrode; \n d) a bipotentiostat counter electrode; and \n e) a control circuitry connected to the electrodes, the control circuitry adapted to measure and control the voltage difference between the reference electrode and the first and second working electrodes and further adapted to output the pH signal indicative of the pH based on measured first current flow and potential through the first working electrode and the hydronium generation signal indicative of the amount of hydronium ions generated based on measured second current flow through the second working electrode; and \n code that determines the alkalinity of the aqueous sample based on the pH signal and the hydronium generation signal.
