Lignin content of biomass

Determination of the acid-insoluble and acid-soluble lignin content of biomass samples.

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.

The lignin content is reported as wt-% of the initial sample on an oven-dry basis.
