In-depth chemical characterisation of biomass Chemical characterisation of biomass and bio-based materials requires knowledge about the material itself and which technique to use for analysing a given compound. RISE PFI has through our various research projects built a broad experience about characterisation of a wide range of biomasses. Our selection of state-of-the art instruments combined with a series of well-established characterisation techniques enables us to characterise the composition of well-known and emerging biomasses.
