Patent abstract
A method is provided for measuring hydrophobic contaminants distributed in paper pulp suspension. The method comprises: adding a fluorescent dye (18) to the paper pulp suspension (12) including fibers and hydrophobic contaminants, the dye (18) interacting with the hydrophobic contaminants of the paper pulp suspension (12); submitting the paper pulp suspension (12) including the fibers, the hydrophobic contaminants, and the dye (18) to light characterized by a wavelength exciting the dye (18) to produce light emission signals; and detecting the light emission signals and evaluating the signals to measure the hydrophobic contaminants.
