Biorefinery Test Methods

Within our research we have defined analytical protocols for analysis of new sample types from the biorefinery, e.g. lignin samples. These test protocols originate from “best practice” and existing methods for wood and pulp. We have validated the methods and determined the repeatabilities. In order to facilitate lignin research and commercialization, we want to share these test methods with anyone interested in lignin characterization.

Initially we share seven test methods concerning analysis of lignin purity, molecular and thermal properties.

You can order, free of charge, our Biorefinery Test Methods by sending an email to any of our contact persons. We will also gladly receive feedback and discuss lignin properties, specifications, analysis needs and other issues relevant to biorefining!
