Allyl Ethyl Ether Polysiloxane as Stationary Phasefor Capillary Gas Chromatography

Polysiloxane with allyl ethyl ether as the side chain has been synthesized and used as stationary phase for capillary gas chromatography. The chromatography performance of these columns have been evaluated. The new stationary phase is proved to have high column efficiency and can easily coated using a static method, and its thermostability is up to 270 ℃, which is suitable for the separation of alcohols, esters and white spirit.
