The gas chromatographic separations of aromatic compounds using special mixed sta-tionary phases consisting of pp-β-CD+AgNO₃, pp-β-CD+TlNO₃, pp-β-CD+di-n-butly phthalate, pp-β-CD+BPBHpB liquid crystalline, and bentone-34+AgNO₃ were investigated. Besides pp-β-CD+di-n-butyl phthalate, most of the separations deviated from the additivity and a synergistic effect was observed. The separation effects depend on the temperature and how mixing is accom-plished.
