New chiral stationary phases of polydimethylsiloxane anchored with (S)-(Γ)-t-leucine derivatives were provided for use in enantiomer separation of pharmaceuticals by capillary gas chromatography. Fifteen pharmaceuticals were separated into their enantiomeric pairs by converting them into pentafluoro
