Simultaneous ion-pair chromatography of inorganic anions and cations using on-column derivatization with chelating agents and UV detection

Covalently Bonded Polymeric Zwitterionic Stationary Phase for Simultaneous Separation of Inorganic Cations and Anions

“…Several techniques such as connected cation- and anion-exchange columns, mixed-bed ion-exchange columns, zwitterionic micelle-coated columns, ion-exclusion chromatography mixed with cation-exchange chromatography, and complexing techniques − have been applied in order to separate inorganic anions and cations simultaneously in a single chromatographic run with a single eluent. A particularly interesting concept is the separation mode termed zwitterion-pair chromatography, which was introduced by Knox and Jurand in the early 1980s .…”
