一般說明
氨基柱最常用于分离单糖和二糖。作为正相应用，氨基塔可用于石油工业（参见SUPELCOSIL™ LC-NH2-NP HPLC色谱柱章节，以了解更多详情）。
硅胶基质的 SUPELCOSIL LC-NH2 色谱柱分离单糖、二糖和一些三糖时其出峰顺序通常是，随分子量的增大化合物保留时间延长。随着水:乙腈在流动相中的比例增大，保留时间减小。更多信息请参阅 T397126（SUPELCOSIL LC-NH2 色谱柱中的糖）。

An analytical method was developed and validated for the determination of maltodextrin in raw milk, using high-performance liquid chromatography with evaporative light scattering detection. Maltodextrin content was evaluated in adulterated raw milk using a Supelcosil LC-NH2 (25cm×4.6mm) column and isocratic
