Fiber composition important for pulp quality

Characterizing pulp often involves an analysis of the fiber composition of a fiber meter to check the quality of the pulp. It is important both in research projects and development projects in process and product.


RISE conducts many projects with several different types of raw materials, which place great demands on the fiber analyzer. We can, after a mild delignification of the material, for example measure on the starting material wood and annuals. Then, of course, we use the meter to analyze pulps according to the different process steps in the mills and also from the corresponding pulp produced in the laboratory.

The most common fiber properties are fiber length, fiber curl, fiber coarseness and fiber width as well as fines and kinks. It is also possible to get distributions for each property as a fingerprint for the pulp.

Pulp technology

The pulp production plays a central role in the bioeconomy, the transition to a fossil-free society and circular processes. The main part of fiber line is the cooking, where wood is treated with chemicals in order to liberate the …

Analysis of anthraquinone in anthraquinone products and dispersions

Anthraquinone consists of yellow acicular crystals and is a form of dispersion used in the cooking of sulphate pulp to improve yield. To get a consistent quality of the process, it is important to know the exact amount of anthraqu…

Light microscopy quickly shows small details

With light microscopy, you can quickly get an overview of the problem and all images are displayed in color. It is often used in connection with product development, problem solving and support to end customers. To gain an underst…

Scanning electron microscopy sees surface structure and elements

Processes are often warm and humid that create good environments for bacteria, precipitates and other undesirable phenomena that contribute to disruption and degradation of end products. Scanning electron microscopy (SEM/XDS) has …

Separation of chemical compounds

Separating and purifying various chemical liquids such as cooking liquids, yeast tanks and black liquor is important in traditional forest industry process liquids and materials, as well as in the biorefinery area.

Analyzes for raw material control

When you buy new chemicals, it can be good to know that the new one is as good as the old chemical. We can help you analyze a number of chemicals.
