Equisil BDS CPS is a high-performance HPLC column featuring a cyano-bonded stationary phase on base-deactivated silica (BDS). This combination provides moderate hydrophobic retention, enhanced polar selectivity, and excellent peak shape, particularly for basic, polar, and aromatic analytes. The base-deactivated surface reduces unwanted silanol interactions, improving reproducibility and robustness — especially in reversed-phase methods using low buffer concentrations or where acidic and basic compounds are present. Equisil BDS CPS is suitable for both reversed-phase and polar normal-phase applications.
Equisil BDS CPS offers versatile CN selectivity with improved deactivation – ideal for robust and reproducible chromatography of polar, basic, and moderately hydrophobic compounds.
