“…They demonstrated good separation of organic anions and inorganic anions and multimode retention mechanism were observed. More recently, Takeuchi et al demonstrated the effective separation of inorganic anions on a commercial available silica column designed for hydrophilic interaction liquid chromatography [9]. The pyridine functional group containing in the stationary phase served to be the effective ion exchange sites when operated in acid eluent.…”

“…This is the opposite elution order compared to the common IEC mode. 23 This result implies that the hydration degree of the analyte anions is the most important factor in deciding the elution order. Anions that have smaller radii have a stronger electrostatic force per unit area, and therefore would be strongly hydrated.…”

“…All samples were well-separated using 100 mM NaCl as the eluent; the elution order of the samples was the same as those obtained by ion-exchange chromatography. 19 However, when lower concentrations of NaCl were used, a decrease in the retention time in all model ions was observed (the elution profiles are shown as Fig. S2 in Supporting Information).…”

Zwitterionic monolithic columns were synthesized by a one-pot reaction using [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide, ethylene dimethacrylate, methanol and 2,2′-azobis(isobutyronitrile) as the monomer, cross-linker, porogen and initiator, respectively. The optimum conditions for polymerization and the efficiency of the prepared columns were examined for ion chromatography. The separation of five kinds of inorganic anions was achieved. The back pressures were monitored as increasing flow-rate, and the resulting plate heights (i.e. height equivalent of a theoretical plate, HETP) of SCN -were calculated at the inspected flow-rates. It was found that the increment rates of both the back pressure and HETP were rather slight. Mobile phases containing various cations or acid increased the retention times of the anions. Divalent cations could be separated, while monovalent cations could not be resolved due to their weak retention on the stationary phases.
