Ultrasep ES 100 Phenyl is a silica-based HPLC column with a 100 Å pore size and a phenyl bonded phase. This stationary phase provides π–π interactions in addition to hydrophobic retention, enabling improved selectivity for aromatic compounds, conjugated systems, and analytes with electron-rich groups.
The phenyl functionality delivers orthogonal selectivity compared to C18 or C8 columns, making it a valuable tool in method development and for the separation of compounds with only subtle structural differences.
Ultrasep ES 100 Phenyl delivers reliable aromatic selectivity and strong performance – the versatile choice for reversed-phase HPLC separations of aromatic and structurally related compounds.
