Abstract:The increased interest in utilizing lignin as a feedstock
to produce
various aromatic compounds requires advanced chemical analysis methods
to provide qualitative and quantitative characterization of lignin
samples along different technology streamlines. However, due to the
lack of commercially available chemical standards, routine quantification
of industrially relevant lignin oligomers in complex lignin samples
remains a challenge. This study presents a novel method for universal
quantification of lignin dim… Show more
“…The chromatogram showed baseline separation of all reference compounds in less than 10 min, and the response factors of the tested dimers did not differ significantly from one another, suggesting that this strategy is well suited for quantifying lignin dimers and oligomers. 95 3.1.2 Molecular weight characterization (GPCMaldi-LC-MS, LTQ-Orbitrap Elite, ESI-MS, and FT-ICR-MS). Another important index for characterizing these oligomeric products is the profile of their molecular weight (or molecular mass) distribution.…”
