Kw. Talmadge et al., HPLC SEPARATIONS OF A BROAD-SPECTRUM OF SMALL MOLECULAR-WEIGHT ANALYTES ON CATION-EXCHANGE COLUMNS, American laboratory, 29(24), 1997, pp. 37
The use of ion-exchange resins is investigated for separations that do
not depend on ion exchange per se is investigated. Several mechanisms
for separation take place: ion exclusion, ion exchange, ligand exchan
ge, size-exclusion, and reversed-phase partitioning.
