Equisil Phenyl is a reversed-phase HPLC column based on fully porous, high-purity silica, modified with phenyl functional groups to enable π–π interactions with aromatic compounds. This phase offers moderate hydrophobicity and unique selectivity for aromatic analytes, structural isomers, and conjugated systems. Equisil Phenyl is ideal for pharmaceutical, environmental, and chemical applications where traditional alkyl phases such as C18 or C8 may not offer sufficient resolution.
Equisil Phenyl provides targeted reversed-phase selectivity for aromatic-rich compounds – ideal for challenging separations where π–π interaction is beneficial.
