Detailed information on the chemical structure of lignin is a key factor in understanding lignin reactivity in various biorefining processes and for industrial utilization of technical lignins. Therefore, reliable, comprehensive and productive analytical methodology is of primary importance in understanding lignin molecular structure. The analytical methods for lignin analysis could be divided on spectroscopic methods (specifically quantitative NMR methods), wet chemistry analysis of specific functional groups and degradation methods to assess specific interunit linkages. This paper discusses advantages and limitations of various methods in the analysis of native and technical lignins, correlation between major analytical techniques and suggests our vision on the best analytical strategy for specific classes of lignin substrates.
