CT-Sil CN

Dual-Mode Cyanopropyl Phase for Polar Compound Separation

CT-Sil CN is a cyanopropyl-modified HPLC column built on high-purity, fully porous silica. This versatile phase supports both reversed-phase and normal-phase chromatography, offering moderate hydrophobicity and strong dipole interaction capabilities. CT-Sil CN is ideal for the separation of polar analytes, aromatic compounds, and structural isomers, especially when traditional C18 or C8 phases are insufficient.

CT-Sil CN provides reliable dual-mode separation performance – a flexible column for challenging polar analytes in both reversed-phase and normal-phase HPLC.
