Abstract: A method of measuring macro and micro stickies in a recycled sample containing pulp fibers is disclosed. The method includes forming a slurry of the recycled macro stickies and a liquid and using a first separation device to separate out the macro stickies and the pulp fiber while collecting the screenate. The macro stickies and the pulp fibers are then washed with additional liquid to further separate out any macro stickies while again collecting the screenate. The macro stickies are then removed from the first separation device and are measured. The method also includes agglomerating the micro stickies in the screenate to form agglomerated micro stickies. The screenate is routed through a second separation device to separate out the agglomerated micro stickies. The agglomerated micro stickies are then removed from the separation device and are measured.
