Fast and cost-effective quality control for pulp and paper Simultaneous multi-parameter analysis by near infrared spectroscopy (NIRS)





NIRS for faster and better quality control 02

Providing consistent product quality is essential for pulp and paper producers to delight their custom-ers. At the same time, in order to stay competitive, cost reduction and improved efficiency is key. From wood property assessment to quality control of intermediates to the final product, Metrohm NIR solutions provide you easier and faster quality control.

In wood processing and pulp and paper manufacturing Metrohm offers NIR solutions for fast and reliable routine knowledge of wood characteristics and monitoring of quality control of wood, pulp, liquor, and paper pro-production steps are essential to ensure optimal raw ducts. NIRS requires no chemicals for analysis and can be material utilisation and to guarantee product quality. For directly applied in the quality control process. Reliable process monitoring and quality control throughout the results of important chemical and physical properties are manufacturing cycle, there is a need for a cost-effective provided in a matter of seconds and reliable measuring system that instantly provides results for important analytical parameters.
