Abstract:
Paper pulp is added to a stain solution. The stain solution and pulp fibers are mixed to form a slurry. Samples are removed from the slurry and are admixed with dilution water and a bleach. Then, the fibers are moved into a flow cell (20) where they are subjected to a light source (40) adapted to stimulate fluorescence from the stained pulp fiber.
