Mixed bed ion-exchange (MBIE) columns containing alumina and silica were evaluated for the simultaneous separation of anion and cation analytes. At the mobile phase pH used alumina provides anion exchange sites while silica provides cation exchange sites. Since alumina and silica exhibit weak acid a

## Abstract A simultaneous separation of anionic, cationic, and neutral compounds was carried out in capillary LC using a mixedโ€bed column of zwitterionic hydrophilic and anionโ€exchange stationary phases. The combination in stationary phases was suitable to retain anionic, cationic, and neutral ana
