Base material silica gel, zwitterionic polar phase with ammonium – sulfonic acid modification.... more
Base material silica gel, zwitterionic polar phase with ammonium – sulfonic acid modification. Polar analytes are more strongly retained than nonpolar compounds. This behavior is inverse (orthogonal) to RP materials like, e.g., C18 or C8.
