A new ionic liquids grafted polysiloxane used as stationary phase for capillary gas chromatography (CGC) is described. The stationary phase of 1-vinyl-3-hexylimidazolium hexafluorophosphate anchored to polysiloxane (PNMS-[VHIm][PF6]) was synthesized, characterized and coated onto capillary columns by static coating. The results show that the present stationary phase exhibits a very good chromatographic resolution and selectivity for Grob test mixture and alcohols with baseline resolution and symmetry peaks. The present work suggests that novel stationary phase has a great potential for further development and application. (C) 2069 Mei Ling Qi.
