Effects of Acetonitrile Concentration on Elution Time (SZ5532)
The base material of the packing material of SUGAR SZ5532 is the gel developed for adsorption & partition mode. It is highly cross-linked and its swelling and shrinkage is very small. The counter ion is Zn2+. Zn2+ forms a complex with saccharides but, when the counter ion is Zn2+, saccharides are not so strongly reteined by ligand exchange mode. And, when organic solvents are added in the eluent, saccharides and sugar alcohols are reteined by adsorption & partition mode and their elution volumes become larger by inceasing organic solvent concentration.
