Relevant parameters for the hardening of acid catalyzed and water based adhesives (e.g. MUF) are certain wood characteristics such as water absorption capacity, pH-value, buffering capacity towards acid and extractive content. This study was performed to characterize these parameters for beech (Fagus sylvatica L.) and ash (Fraxinus excelsior L.) with and… (More)
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… (More)
Anatomical differences were seen between tumorous and normal wood whereas noticeable differences were not detected in the chemical composition.
