Aminex HPX-42A 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 silver-form, 300 x 7.8 mm column provides fast, high-resolution oligosaccharide analysis. It separates oligosaccharides to D-11 in approximately 25 minutes.
