We are working toward the development of an instrument for the continuous, on-line measurement of the lignin concentration in wood pulp. The instrument is based on laser induced fluorescence of the wood pulp and is to be used as a primary sensor for both feedback control of the pulping and feedforward control of bleaching. We report here the results of a series of laboratory tests that characterized the fluorescence properties of wood pulp and demonstrated a correlation between various fluorescence functions and the Kappa number of the pulps as determined by TAPPI Procedure T236.
