The gas chromatographic properties of a new oligo(ethylene oxide)-substituted (glyme) polysiloxane stationary phase and an 18-crown-6-substituted (crown) polysiloxane phase were compared to Carbowax 20M and a bonded poly(ethylene glycol) (Bondable PEG).The glyme polysiloxane was found to have an operational temperature range of 20-280 deg C and a selectivity similar to that of Carbowax 20M.The crown polysiloxane was found to have unique selectivity, partly because of the size and shape of the crown ether cavity and the structures of solute molecules.Selected applications including the analysis of alcohols, fused oils, and nitrogen heterocycles are demonstrated.
