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 phenyl-modified stationary phase has π-electrons. The hydrophobic and π-π nteractions between the stationary phase nd the solute show unique separation characteristics compared with the alkyl-bonding stationary phases, such as C18, C8, and C4
