Equisil CPS-2 is a reversed-phase HPLC column , featuring a cyano-bonded stationary phase on fully porous, high-purity silica with enhanced surface deactivation. The CPS-2 bonding offers the classic dual-mode selectivity of cyano phases — combining moderate hydrophobic retention with polar interaction capabilities — while minimizing unwanted silanol effects for improved peak symmetry and reproducibility. Designed for reversed-phase and polar normal-phase applications, Equisil CPS-2 provides faster elution of analytes that are over-retained on C18 columns, and is well suited for method development involving polar, aromatic, or moderately basic compounds.
Equisil CPS-2 offers reliable CN selectivity with reduced secondary interactions – ideal for modern HPLC workflows requiring fast, polar-selective, and reproducible separations.
