Hamilton RCX-10 And RCX-30 Columns for the Anion Exchange Separation of CarbohydratesHamilton RCX-10 carbohydrate analysis columns are designed for the isocratic and gradient separation of carbohydrates. Samples containing two or three carbohydrates, for example Ice Cream can be quickly separated isocratically while more complex samples like Corn Syrup, require gradient elution to fully resolve all the oligomers (DP1 to DP7).…
Separate Mono and Disaccharides or Carbohydrate Oligomers from DP1 to DP8.Hamilton HC-75 columns separate carbohydrates by ligand exchange and size exclusion mechanisms.HC-75 is a more highly crosslinked gel (7.5%) that utilizes ligand exchange to separate carbohydrates. Calcium, Hydrogen and Lead are available as counter ions. The calcium form column is more commonly used because of its broader applicability.For application e…
