| Abstract: | Three catenary crown ethers used as stationary phase were coated on fused-silica capillary column. Their chromatographic characteristics including efficiency, thermal stability, polarity and selectivity were studied. The results showed that they possessed good chromatographic feature, middle polarity and high selectivity, and that it was suitable for the separation of isomer of alcohols, halohydrocarbons and aromatic hydrocarbons. Based on the results, the separation mechanism was discussed. |
| Keywords: | Catenary crown ether stationary phase retention mechanism gas chromatography |
