The present invention relates to a method for determining a concentration of a corrosion or scale inhibitor in a water sample comprising at least one corrosion or scale inhibitor, wherein said method comprises measuring the current as a function of the potential of one or more water samples thereby determining the concentration of said corrosion or scale inhibitor in said water sample. The present invention also relates to a method for determining the potential of a water sample comprising a corrosion or scale inhibitor, and a method for controlling or monitoring the concentration of one or more corrosion or scale inhibitors in an industrial fluid, and a kit for voltammetry analysis.
