Abstract
A carbon quantifying cell (20) configured to receive a fluid is provided, including two or more electrodes (22) positioned at least partially in the fluid, and meter electronics (21) configured to place an electrical oxidization, polarization, and/or adsorption program across the two or more electrodes (22) and at least partially oxidize carbon materials in the fluid, apply an AC voltage of a predetermined amplitude across the two or more electrodes (22), measuring the resulting AC current across the two or more electrodes (22), wherein a ratio of amplitudes and a phase angle difference provides information for calculating a fluid impedance, receive an electrical response of the fluid to the electrical oxidization, polarization, and/or adsorption program, quantify the carbon materials in the fluid using the electrical response, and detect interfering materials in the fluid using the fluid impedance.
