  • Description: A method of measuring hydrophobic contaminants in a pulp slurry or a papermaking system includes the steps of providing an aqueous paper mill sample, filtering the aqueous paper mill sample to produce a filtrate comprising particles, and collecting an image of the particles in a measured volume of the filtrate. The method also includes the steps of analyzing the image to determine a size and morphology of the particles in the measured volume of filtrate, identifying spherical particles having a size of from about 1 micron to about 20 microns in the measured volume of filtrate, and quantifying a number of the spherical particles having the size of from about 1 micron to about 20 microns in the measured volume of filtrate. This method is useful for papermakers for deposition diagnostics, prevention, and contaminant control treatment optimization.
