Carbohydrate ition of Extractive-free Wood and Wood Pulp by Gas-liquid Chromatography 气相色谱法测定无抽提物木材和木浆中的碳水化合物
发布日期: 2021-11-01
该方法(1,2)用于测定五种主要单糖,它们定义了木材和木浆的碳水化合物组成。定量和绝对测定的成分为葡聚糖、甘露聚糖、阿拉伯多糖、木聚糖和半乳聚糖。可测定低至0.1%的单个组分浓度。该方法适用于无抽提木材以及木浆。
This method (1, 2) is used to determine the five principal monosaccharides which define the carbohydrate composition of wood and wood pulp. The constituents determined quantitatively and on an absolute basis are glucan, mannan, arabinan, xylan and galactan. Concentrations of the individual components as low as 0.1% can be determined. The method is applicable to extractive-free wood as well as to wood pulp.
