Abstract
The invention relates to a method for determining a scale inhibitor concentration in a sample comprising at least a first scale inhibitor, which is a synthetic organic compound comprising at least one ionized group. The method comprises optionally diluting and/or purifying the sample, and allowing the sample to interact with a reagent comprising a lanthanide(III) ion. The sample is excited at a first excitation wavelength and a sample signal deriving from the lanthanide(III) ion is detected at a signal wavelength by using time-resolved luminescence measurement, and the concentration of the at least first scale inhibitor in the sample is determined by using the detected sample signal.
