   Sammanfattning : In the present thesis, capillary zone electrophoresis (CZE),matrix-assisted laser desorption/ionization time-of-flight massspectroscopy (MALDI-MS) and size-exclusion chromatography incombination with off-line MALDI-MS (SEC/MALDI-MS) have beenapplied successfully to the analysis of wood and pulpcomponents.The carbohydrate compositions of pulp and holocellulosesamples, as well as of isolated hemicellulose preparations,were determined employing enzymatic hydrolysis and subsequentanalysis of the saccharides released by CZE.
