Abstract

The gas chromatographic properties of a new oilgo (ethyiene oxkle)-wbstltuted (glyme) polysiloxane statlonary phase and an 18crown-&substltuted (crown) polyslioxane phase were compared to Carbowax 20M and a bonded poly (ethy1ene glycol)(Bondable PEG). The glyme pdyslloxane was found to have an operational temperature range of 20-280 OC and a seiectlvlty slmilar to that of Carbowax 20M. The crown polyslloxane was found to ...
