Abstract [en]

In 1999 Tembec Industries and the National Renewal Energy Laboratories worked together in developing a methodology to use Near-infrared (NIR). Technology of in-house pulp fibre quality properties Q99 and Q97. The initial results with dry samples of pulp were encouraging. the wet samples results were initially disappointing using the standard chemometric techniques. Svante Wold developed a new chemometric method called Orthogonal Signal correction (OSC), which was used to obtain a good correction of Q99 in the wet pulp samples.
