Aminex HPX-87N

Aminex HPX-87N 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 sodium-form, 300 x 7.8 mm column is optimized for the analysis of sugars in samples with high salt concentrations, such as beet sugars. It is compatible with salts, so there is no need to desalt samples before analysis.
