The results showed that the substances with exact same substitutions on the benzene ring as lignin units had good stabilities in the pyrolysis process with good lineabilities of peak response area to the mass curves, which implicated these substances can be applied as calibration standards in the ...
When associated with on-line pyrolysis apparatus, it can be used for quantitative lignin analysis in order to predict the lignin content on paper and pulp, employing stabilities of aromatic monomers produced via the thermal degradation of lignin (Hou et al., 2013). HPLC can provide additional ...
