Notes:
In this paper, two new open crown ether polysiloxane stationary phases were prepared for capillary gas chromatography. Chromatographic characteristics, including column efficiency, operational temperature range, thermal stability, and polarity were studied. The open crown ether polysiloxane was found to have unique selectivity for alcohols, aromatic hydrocarbons, and nitrogen-containing compounds. The separation mechanism and various thermodynamic parameters are discussed.
