Hamilton Company HC-75 (Ca2+) 9 µm 4.1 x 250 mm 79431

HC-75 columns separate compounds through ligand exchange. The 8% cross-linked HC-75 uses ligand exchange as the primary mechanism of separation. The different forms of the HC-75 (Hydrogen, Calcium and Lead) each provide a unique selectivity for separating varying types of charged analytes based on electronegativity toward the counterion. The higher carbohydrate oligomers elute first while the smaller di- and monosaccharaides elute later.
