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 NH2-modified stationary phase can be used in the HILIC, IEC, and NP modes. The HILIC mode is for the separation of polar compounds, such as carbohydrates. In the IEC mode, the NH2 phase works as a weak anion exchanger in aqueous buffers at a low pH. In the NP mode, it is useful for separating basic compounds because the plus charge of the surface prevents ionic interaction with basic compounds.
