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 Nitril-bonded phase is the most polar and the least retentive RP mode. In the case of the RP mode, the CN-modified phase is for the separation of extremely hydrophobic compounds. In the case of the NP mode, the CN-modified phase shows more uniform surface activity and often increased resistance to possible dissolution compared to bare silica.
