Lignin is the largest source of bio‐based aromatic compounds in nature, and its valorization is essential to the sustainability of lignocellulosic biorefining. Characterizing lignin‐derived compounds remains challenging due to the heterogeneity of this biopolymer. Tandem mass spectrometry is a promising tool for lignin structural analytics, as fragmentation patterns of model compounds can be extrapolated to identify characteristic moieties in complex samples. This work extended previous resonance excitation‐type collision‐induced dissociation (CID) methods that identified lignin oligomers containing β–O–4, β–5, and β–β bonds, to also identify characteristics of 5–5, β–1, and 4–O–5 dimers, enabled by quadrupole time‐of‐flight (QTOF) CID with energy‐resolved mass spectrometry (ERMS). Overall, QTOF‐ERMS offers in‐depth structural information and could ultimately contribute to tools for high‐throughput lignin dimer identification. [ABSTRACT FROM AUTHOR] |
