CT-Sil is a silica-based HPLC column series designed for normal- and reversed-phase separations with excellent reproducibility, peak shape, and retention stability. Based on fully porous, high-purity silica and modified with classical bonding chemistries such as C18, CT-Sil columns offer strong hydrophobic retention for non-polar and moderately polar analytes. This product line is ideal for routine and regulated HPLC applications, including pharmaceutical, chemical, and food analysis.
CT-Sil columns offer classical reversed-phase selectivity and reliable retention – ideal for labs looking for stable performance in standard HPLC workflows.
