Abstract

Different model compounds for lignin hemicelluloses and pectins were studied by timeofflight secondaryion mass spectrometry ToF–SIMS Mass spectra of Klason lignin from normal and compression spruce wood aspen wood and wheat straw were compared Spectra of brominated spruce and aspen wood sections showed fragment ions attributed to brominated guaiacyl and syringyl units in lignin at m/z 215 217 229 and 231 and m/z 245 247 249 and 261 respectively Spectra of mono oligo and polysaccharides showed fragment ions at m/z 127 and 145 characteristic for hexose units and ions at m/z 115 and 133 characteristic for pentose units The same ions were detected in spectra of delignified spruce and aspen wood sections Labelling of anionic groups by Sr2+ ions followed by ToF–SIMS analysis showed that pectins were present at specific locations on the surfaces of spruce and aspen wood sections still after delignification with hydrogen peroxide in acetic acid
