Summary
A novel bonded phase for reversed-phase HPLC was synthesized in two steps. Octylamine was first reacted with β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (β-ECTS) and then the intermediate product was coupled onto porous silica. The prepared packing was characterized by elemental analysis, solid-state13C NMR and Fourier transform infrared (FT-IR). Chromatographic evaluations were carried out by using a mixture of organic compounds including acidic, basic and neutral analytes and methanol-water as binary mobile phase. The results showed that the stationary phase has excellent chromatographic properties and is resistant to hydrolysis between pH=2≈8. It can be used efficiently for the separation of basic compounds.
