Measuring the Molecular Weight Distribution of Lignin

Molar mass and molar mass distribution is a fundamental property of lignin and an important characteristic for understanding and predicting polymer performance. We have equipment specialized for measuring molar mass distribution o…

Analyses of deposits

Deposits, stickies, scales and contaminations in the pulp mills often causes disturbance and loss of efficiency in the processes and affects the quality of the final products.

Chemical analysis of material composition

We can help with chemical analyzes to identify the composition and origin of unknown samples. The analyzes can often be started immediately, without extensive planning and preparation

Proficiency testing for biorefinery laboratories

What is the quality of your routine analyses? Are your procedures fit for purpose? Participating in proficiency tests is a convenient way to find out! RISE annually organizes tests for a number of chemical analyses used in pulp, p…

Lignin analyses/lignin characterization

The properties of lignin samples are to a great extent influenced by their chemical and molecular structure. RISE has long experience and advanced equipment for characterization of lignin on different structural levels.
