ABSTRACT:
An apparatus and process for testing the uniformity of a papermaking pulp with respect to the lignin associated with individual fibers comprising substantially simultaneous analysis of individual fiber length and fluorescence of the lignin associated with such individual fiber. The ratio of the lignin mass over the fiber length has been found to be proportional to the Kappa Number.
