- VA HPLC column (analytical), NUCLEOGEL SUGAR Pb, 10 µm, 300x7.8 mm
Polymer-based HPLC phase for separation of sugars. Sulfonated polystyrene / divinylbenzene resins in Pb ionic form. Separation mechanism includes steric exclusion, ligand exchange and partition effects, ligand exchange being the predominant force, since the hydrated metal ions form strong interactions with the hydroxyl groups of the sample molecules. The intensity of these interactions decreases in the sequence Pb, Ca, Na.
