【Abstract】 A new stationary phase,side chain liquid crystalline polysiloxane containing crown ether,was developed and used in capillary column gas chromatography. This stationary phase can be easily coated on the fused silica tubing,and possesses a high efficiency and moderate polarity. It exhibits the retention properties both of liquid crystal and of crown ether stationary phases. This phase is suitable for the separation of a variety of isomeric compounds.更多还原
