Stationary phase cinchona-alkaloid-bonded

Cinchona-Alkaloid-Bonded Chiral Stationary Phase 144... [Pg.131]

The cinchona alkaloid-based stationary phases are chiral stationary phases where quinine/ quinidine are chemically bonded to a silica gel matrix. The interaction between the selectand and selector is based on charge transfer n-n interactions as well as ion pairing with the selector. They operate under aqueous-organic mobile phases or mixtures of organic solvents such as hexane-alcohols. [Pg.235]
