Laser Desorption Fourier Transform Mass Spectrometry of Natural Polymers
Natural polymers, humic acid and lignins, were investigated by laser desorption (LD) Fourier transform mass spectrometry. In the vapor phase under LD conditions only positive ions of humic acid were observed up to m/z 700. Under the same conditions all the lignins investigated prefer to form negative ions of the individual oligomers at well-defined mass spacings and with a distribution from m/z several hundred to 3OOO. Three sequences with Am-444 confirm the existence of stable trimer building blocks in the coniferous lignins.
