Equisil BDS Phenyl is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with phenyl functional groups and treated with base deactivation (BDS). This combination allows for π–π interactions with aromatic analytes while minimizing silanol-related peak tailing, especially for basic and polar compounds. The column offers moderate hydrophobic retention and distinct selectivity compared to standard alkyl phases like C18 or C8. Equisil BDS Phenyl is ideal for applications requiring improved resolution of aromatic compounds, isomers, and electron-rich analytes.
Equisil BDS Phenyl offers selective aromatic retention with excellent peak shape – an ideal column for resolving complex aromatic and basic analytes in reversed-phase HPLC.
