Near-Infrared Spectroscopy Application Note NIR–9 Determination of hardwood/softwood content in wood products by near-infrared spectroscopy Near-infrared spectroscopy is ideally suited to monitor the hardwood and softwood content in pulp and paper products. The herein described method bases on the fact…

NIR Application Note NIR-32 Determination of cotton linter to wood ratio in cellulose This Application Note shows that Vis-NIR spectroscopy can be used to determine the cotton linter to wood ratio in cellulose samples. This ratio is important in pulp…

NIR Application Note NIR-39 Vis-NIR spectroscopic analysis of wood pulps for multiparameter prediction This Application Note shows that visible near-infrared spectroscopy (Vis-NIRS) can simultaneously determine six pulp parameters (kappa number (titration), applied density (densimeter), pulp freeness (CSF), breaking strength (SCT),…
