Characterization of different wood samples using a new combined method of evolved gas analysis and pyrolysis-gas chromatography/mass spectrometry

摘要

Evolved gas analysis (EGA) in combination with analytical pyrolysis is presented as a new technique for rapid investigations into wooden materials. In a first analytical step, the thermal behaviour of three wood samples was determined by EGA. Based on these results, analytical pyrolysis-gas chromatography/mass spectrometry was carried out to investigate the influence of wood-specific thermal behaviour and the chemical composition on the results. Furthermore, the influence of sample mass and particle size was examined.
