Abstract
The present invention relates to a method for determining hydrolysis degree and charge density of polyelectrolyte or phosphonate in a sample. In the method the sample is mixed with a reagent comprising a lanthanide(lll) ion. The mixture is excited at an excitation wavelength and a signal deriving from the lanthanide(lll) ion is detected by using time-resolved fluorescence measurement, followed by determining the hydrolysis degree and the charge density of the polyelectrolyte or phosphonate by using the detected sample signal.
