Aminex HPX-87P 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 lead-form, 300 x 7.8 mm column is tailored for the separation of cellulose-derived monosaccharides. It is used in analyses of pentoses and hexoses in wood products, especially cellobiose, glucose, xylose, galactose, arabinose, and mannose. It also provides excellent resolution of sucrose, lactose, and fructose in dairy products.
