Laser micropyrolysis GC-MS of lignin

The potential for using lasers as a highly directional thermal source in analytical pyrolysis studies is further investigated by the laser micropyrolysis GC-MS analysis of lignin moieties. Two woods representative of the main types of lignin (i.e. gymnosperm/guaiacyl producing and angiosperm/syringyl and guaiacyl producing) were separately analysed by both laser micropyrolysis GC-MS and the longer used pyroprobe pyrolysis GC-MS. High levels of correlation were observed from the laser and pyroprobe pyrograms of both lignins. (C) 2002 Elsevier Science B.V. All rights reserved.
