气相色谱法已广泛应用于植物中多糖类和生物物质中天然糖的测定。首先将多糖、低聚糖水解成单糖,再制成受热能挥发且不容易分解的衍生物,例如糖硅醚、糖醇醋酸酯、糖腈乙酰酯、糖的二乙基二硫缩醛三甲基硅醚等,才能用气相色谱法分析。木材和浆粕的单糖组成分析中水解是重要的步骤,通常使用硫酸法水解。硫酸
Gas chromatography has been widely used in the determination of natural sugars in polysaccharides and biological substances in plants. First, polysaccharides and oligosaccharides are hydrolyzed into monosaccharides, and then heat-volatile and non-decomposable derivatives such as glycosyl ether, sugar alcohol acetate, sugar alcohol acetyl ester, sugar diethyl disulfide Trimethylsilyl ether, etc., can be analyzed by gas chromatography. Hydrolysis is an important step in the monosaccharide compositional analysis of wood and pulp, and is usually hydrolyzed using the sulfuric acid method. sulfuric acid
