- Abstract
Lignin is the second most abundant natural polymer and a promising alternative energy source for conventional fossil fuels. In this study, we investigated transformations of lignin compounds under artificial UV light conditions at the molecular level. Such light-induced changes of composition profiles in nature after sun exposure have been studied for crude oil in the petroleomics field. We applied a similar high resolution mass spectrometry experimental strategy to lignin and demonstrated various data processing methods to reveal the characteristic differences between the extremely complex data sets of two sample sets, one native control before and one sample after photo-irradiation, using Fourier transform ion cyclotron resonance-mass spectrometry.
