A rapid modified gas chromatographic method for carbohydrate analysis of wood pulps

摘要: The current procedure of TAPPI Test Method T 249 cm-85 for carbohydrate analysis requires acetylation alditols. Preparation alditol acetates involves a series evaporation steps. This investigation is an attempt to improve the efficiency this gas chromatography method. Using 1-methylimidazole as catalyst, alditols in presence borates has been successfully accomplished. eliminates need Analysis number different pulp samples, using modified method, showed accurate and repeatable results. monosaccharide compositions were comparable with conventional Application : method makes it possible characterize wood carbohydrates faster than T249 cm-85, without losing accuracy.
