General description
Silica-based SUPELCOSIL LC-NH2 columns separate monosaccharides, disaccharides, and some trisaccharides, with elution generally in order of increasing molecular weight. Retention decreases as the proportion of water:acetonitrile in the mobile phase is increased. For more information, request T397126 (Sugars on SUPELCOSIL LC-NH2 Columns).
The amino column is most often employed for the separation of mono- and disaccharides. As a normal-phase application, amino columns are used in the petroleum industry (see SUPELCOSIL™ LC-NH2-NP HPLC Columns for additional details).

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
