CT-Sil C18 is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with octadecyl (C18) groups for strong hydrophobic retention. Designed for routine analysis, this phase provides stable performance, reproducible retention, and good peak shape for a wide range of non-polar and moderately polar analytes. CT-Sil C18 is ideal for pharmaceutical, food, and environmental testing where consistent reversed-phase behavior is required.
CT-Sil C18 delivers classical reversed-phase selectivity and dependable performance – an excellent column for standard HPLC workflows.
