Chromatographic Properties of Tetradecylamine Bonded Stationary Phase for Reversed-Phase Liquid Chromatography
|
Abstract:
A novel bonded stationary phase, tetradecylamlne bonded stationary phase(TABP), for reversed-phase HPLC was prepared by bondingl-tetradecylamlne to YWG-80 silica gel through 3-glyci- using aromatic compounds as analytes and methanol-water as binary mobile phase. The organic components and peakshape. The relative retention a for ethylbenzene-toluene was found to be 1.66 and the asymmetry factors of basic aniline, p-toluldlne and N, N- dimethylaniline were found to be 1. 26, 1. 21 and 1.10, respec-tively,with the V(methanol):V(water)=55:45 mobile phase. Aniline was eluted before phenol due to the suppress of the ion exchange activity of residual silanols by the internal masking Interaction.
