Equisorb Phenyl is a reversed-phase HPLC column packed with fully porous, high-purity silica particles bonded with phenyl groups. This aromatic stationary phase offers a combination of hydrophobic and π–π interactions, making it especially suitable for the separation of aromatic compounds, structural isomers, and analytes with electron-rich functional groups. The phenyl phase provides an alternative selectivity to C18 and C8 columns and is ideal for use in method development, impurity profiling, and aromatic compound analysis.
Equisorb Phenyl offers distinct aromatic selectivity and reliable reversed-phase performance – a valuable tool for challenging separations involving π–π interactions.
