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.
Sil stationary phase is widely used in normal phase separation. Especially, separation of position isomer and lipid-soluble compounds is effective. HECTOR-M Sil is produced by high purity silica (99.99 % purity) and enhanced mechanical strength.
