Wide range selection of stationary phase supports customer demands from analytical to Semi-prep scale. For reversed phase mode, C18, C8, C4, NH2, CN and phenyl phase are available depend on the polarity. On the other hands, Sil, NH2, Diol, and CN are available for normal phase mode. These normal phase columns cover to separate acidic, neutral, and basic compounds by right choice of stationary phase.
The diol-modified normal phase has a neutral hydroxyl group and is thus a more versatile alternative to silica. The hydrogen bonding on the diol layer is not as strong as with that on silanol on a bare silica surface, and shows improved reproducibility. The diol matrix is very easy wettable and is appropriate for the separation of neutral, acidic, and basic compounds
