Aminex HPX-87K Column

Aminex HPLC columns are packed with a polymer-based matrix (polystyrene divinylbenzene). They separate compounds using the ion-moderated partition chromatography technique. Aminex carbohydrate analysis columns separate compounds using a combination of size exclusion and ligand exchange mechanisms:

In oligosaccharide separations, size exclusion is the primary mechanism. Low crosslinked resins allow carbohydrates to penetrate, and oligosaccharides separate by size.

This potassium-form, 300 x 7.8 mm column is optimized for the analysis of mono-, di-, and trisaccharides in samples such as corn syrup and brewing wort. It exhibits good separations of glucose, maltose, and maltotriose.
