|Title:||A new thermally immobilized fluorinated stationary phase for RP-HPLC|
|Abstract:||A new fluorinated stationary phase was prepared through thermal immobilization of poly (methyl-3,3,3-trifluoropropylsiloxane) onto 5 mu m Kromasil silica particles. The best conditions of immobilization time and temperature were determined through a central composite design and response surface methodologies. Physical-chemical characterization using solid-state (29)Si NMR measurements, infrared spectroscopy and elemental analysis showed that the immobilization process was effective to promote a coating of the support that corresponds to a monolayer of polymer. The stationary phase presents selectivity for positional isomers and good peak shape for basic compounds.|
