The amide ligand was synthesised with high yield. Theresulting amide bonded stationary phase was characterised by SEM, IR and elemental analysis. Theresulting selector bearing a polar amide group is used for the reversed-phase chromatography separationof different classes of thirteen phytohormones (plant hormones). The chromatographic behaviours ofthese analytes on the amide-silica stationary phase were compared with those of RP-C18 column undersame conditions. The effects of different separation conditions, such as mobile phase, pH value,flow rateand temperature, on the separation and retention behaviours of the 13 phytohormones in this systemwere studied. The optimum separation was achieved using reversed-phase HPLC gradient elution with anaqueous mobile phase containing pH¼6.85 potassium phosphate buffer (20 mM) and acetonitrile with a221C column temperature. Under these experimental conditions, the 12 phytohormones could beseparated and detected at 230 or 270 nm within 26 minÖğe HILIC separation and optimization of B vitamins usıng the Ile-PBA-Mix, a mıxed-mode stationary phase(Hitit Üniversitesi, 2017-09) Aral, Tarık; Aral, Hayriye; Altındağ, Ramazan; Çelik, Kadir Serdar
