摘要：
The matrix-supported laser desorption technique proved to be quick, sensitive, and informative in the characterization of lignins. The technique yields the molecular weight distribution directly (for birch lignin up to about 16 000 Da), while the well-resolved fine structure of the spectrum confirms the existence of oligomers from trimers through to nonamers. The hyperfine structure reflects the complicated structure of lignin, constructed of monomeric units that are linked to one another through various types of bonds.
