摘要: The paper presents the results of a study on aryl phases aimed at increase separation selectivity substances containing π electrons, and improving reproducibility retention data. above contain not only carbon chain different length, linking them to support, but also one or two aromatic rings. suitability newly obtained packings for purposes high-performance liquid chromatography was verified basis description surface topography before after modification process. Various physicochemical methods were employed determine effectiveness chemical modification, i.e., elemental analysis, infrared spectroscopy, nuclear magnetic resonance. used polynuclear hydrocarbons budesonide epimers, tested under hydroorganic conditions (water/ethanol, water/methanol, water/acetonitrile). application methanol/water mobile phase new-generation naphthylpropyl stationary 22R 22S diastereoisomers allowed obtention reproducible make qualitative quantitative determinations particular enantiomers.
