Equisil CPS is a high-performance HPLC column featuring a cyano-bonded stationary phase on fully porous, high-purity silica. The cyano phase provides moderate hydrophobicity combined with polar interaction capabilities, enabling fast and selective separations of moderately polar compounds, structural isomers, and analytes with limited retention on standard C18 columns. Equisil CPS offers excellent peak symmetry, short analysis times, and broad solvent compatibility, making it ideal for reversed-phase and polar normal-phase applications in routine and regulated environments.
Equisil CPS from offers versatile cyano selectivity – ideal for analytical HPLC methods requiring short run times, orthogonal selectivity, or enhanced resolution of polar analytes.
