摘　　要：应用硅胶的氨基键合改性方法,研究色谱分离提取葡萄糖母液中低聚糖组分中的同分异构体的工业色谱填料。经红外光谱、元素分析对最后的产物进行表征,考察了该键合相的pH值适用范围。用自合成填料自装色谱柱对该键合相进行了色谱评价。结果表明:改性后硅胶键合相具有较好的色谱性能,且在pH值为2～11时稳定性能良好,可有效地用于低聚糖中的同分异构体的分析分离。In order to separate isomeric compounds from the mother liquor of glucose, industrial chromatography packing material was prepared by the NH2-bond modification of silica gel. The bonded phases obtained were characterized with elemental analysis, and infrared spectrum. Chromatographic evaluations were carried out by using self-made packing material to fill the HPLC column. The results showed that the stationary phase had excellent chromatographic properties and resistance to hydrolysis between pH 2～11. It could be used for the efficient separation of isomeric compounds from oligosacchardes.
