Analyzing cellulose

To ensure high quality pulp production, accurate fibre and pulp analysis is essential. We offer measurements of:

Physical properties: grinding degree (SR/CSF), WRV, sheet, basis weight, thickness, density/bulk, strength and air permeability.
Chemical analyses: Carbohydrates, extract content, phenolic groups, fibre charge, kappa number, metals, viscosity and leachable COD/TOC.

Wood characterisation includes analysis of chemical composition, structure, physical and mechanical properties. We offer measurement of:  

Basic parameters: Dry content, size distribution, bark content, density, thickness and distribution, fibre dimensions.  
Chemical analyses: Metals (e.g. calcium, copper, iron, zinc), carbohydrates, lignin, extractives, ash content, organic chlorine, oxalic acid, carbonyl end groups, uronic acids.  

Physical properties: Viscosity, fibre charge, fibre length and wall thickness, conductivity, pH.  
Specific tests: Alkali resistance, molecular weight distribution, wash loss, leachable COD/TOC, Kappatal, Fock's reactivity, hexanal.  

We also perform wood and pulp analyses, including measurement of alpha, beta and gamma cellulose, as well as contaminants such as stains and dirt.

Fibre analysis is a key process in the pulp and paper industry, providing valuable insights into pulp composition and properties.  

By analysing fibre length, diameter, curl, coarseness and other key parameters, the performance and suitability of the pulp for different applications can be effectively assessed.

RISE offers evaluation of fillers in paper products with focus on several critical parameters. We analyse key properties such as brightness, pH, dryness and viscosity to assess the quality and suitability of fillers in different paper applications.
