Studies on Chromatographic Characteristics and Mechanism of theSide-chain Oxygen Crown Ethers Polysiloxane as Stationary Phases for Capillary Gas Chromatography

Abstract

Abstract: Two new kinds of crown ether, n-undecyloxymethyl-18-crown-6(or 15-crown-5) side-chain polysiloxane were prepared and coated on capillary column. Their chromatographic characteristics including column efficiency, allowable operating temperature range, thermal stability, polarity and selectivity were studied, and their separation mechanism was discussed.

Key words: Stationary phase, Crown ether, Polysiloxane, Quartz glass capillary, Gas chromatogra-Phy
