MONITORING QUALIDADADE OF THE PULP

A method is disclosed for monitoring hydrophobic particles contained in a pulp suspension， the method comprising obtaining (601) a sample from a pulp suspension or a filtrate of the pulp suspension. A dye is added (602) to the sample to stain particles in the sample， wherein the dye is a fluorescent dye. The sample is fractionated (603) to obtain at least a first fraction and a second fraction， wherein the second fraction is a fiber fraction. The method further comprises measuring (604)， for the obtained fractions， fluorescence emitted by the particles in said fractions， calculating (605) an integral of the fluorescence measured for the fractions excluding the fiber fraction， and correlating (606) the calculated integral of the fluorescence to the amount of acetone soluble material in the pulp suspension， and optionally measuring light scattering signal of the particles in said at least first and second fractions.
