The pulp and paper industry has utilized NIR analysis for many years providing qualitative and quantitative information about incoming timber materials and lignin content. Discriminant NIR analysis can be used to determine species, hardwoods from softwoods and sapwoods from heartwoods. NIR can be used as a quick and effective means of determining kappa number in pulp.
Common pulp and paper attributes measured with NIR include: kappa number, lignin content, kraft yield, tall oil, moisture, resin, brightness, wood species, hardwood/softwood ratio, coatings and components analysis (clay, titanium dioxide, fillers, ash).
