Lignin content of biomass

Determination of acid-insoluble and acid-soluble lignin in biomass sample. A solid biomass sample is hydrolyzed and the acid-insoluble residue is filtered out to determine the amount of Klason lignin. Acid soluble lignin is determined from the hydrolysate using UV-VIS-spectrophotometer at 205 nm. The lignin content is reported as wt-% of the initial sample on an oven-dry basis.
