✦ Synopsis

The silicone GE XE-60 has been modified by hydrolysis and coupling with Lvaline-rc,t.-butylamide to introduce a chiral property and by subsequent chnin-opening polymerization with octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane to obtain thermal stability and resolution efficiency. The resulting chiral phases can be used for the separation of amino acid enantiomeric mixtures by glass capillary gas chromatography at operating temperatures up to 200°C. The thermal stabilities, resolution factors and peak-to-peak separations of amino acids obtained with the different phases arc compared.
