Integration of the novel column modification approach with a triptycene-based stationary phase achieves high-resolution performance and inertness towards acids/bases and isomers for capillary GC analysis.
This work reports the synthesis of 2,5-di(4-nitrophenyl)-3,4-di(3,5-difluorophenyl)phenyl grafted polysiloxane (NDPP; containing 12.4% 2,5-di(4-nitrophenyl)-3,4-di(3,5-difluorophenyl)phenyl groups) for gas-chromatography (GC) separation.
This work presents the investigation of p-tert-butyl(tetradecyloxy)calix[4]arene (C4A-C10) as stationary phase for capillary gas chromatographic (GC) separations.
