Molecular weight determination of lignins using electrospray ionisation mass spectrometry (ESI/MS). Preliminary results.


The preliminary results on lignins molecular weight determination using ESI/MS technique are presented. The ESI/MS spectra showed the molecular weight distribution of lignin as well as structural features of oligomers with molecular mass between 500 and 2000 u. The possibility of lignin reactions monitoring in solution using ESI/MS analysis is demonstrated.
