Aminex HPX-87C 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 calcium-form column is the column of choice for most general sweetener analyses. It is optimized for analyzing monosaccharides and also provides class separation of di-, tri-, and tetrasaccharides. The 300 x 7.8 mm column is used primarily for the quantitation of glucose and fructose in high fructose corn syrup and for general monosaccharide analysis. The 250 x 4.0 mm column is appropriate for sugar alcohol separations.
