Abstract [en]
This study describes development of methods for identification and quantification of a set of mono- and diaryl compounds in lignin. The diaryls consist of a set of stilbenes and resinols, while the monoaryls consist of guaiacol, vanillin, acetovanillone and three syringyl counterparts. The methods rely on HPLC-MS and GC-MS. These were quantified in a set of technical lignins and were found to comprise 1 – 11 % of the total mass of the samples.
