Purospher STAR Phenyl, 3µm, 120Å, 150mm x 3mmID, Hibar RT HPLC ColumnPhenyl HPLC columns are the best alternative to RP-8 or RP-18 columns for the separation of aromatic compounds, and compounds containing aromatic groups.
Purospher™ STAR Phenyl can retain analytes via several different mechanisms, including π-π interactions between the overlap of the delocalized electrons on the analyte and the stationary phase
phenyl group, and via partitioning between the mobile phase and the hydrophobic aryl-alkyl phase.
Purospher™ STAR Phenyl columns are based on highpurity silica particles, which provide symmetrical peaks for basic compounds, as well as high stability and excellent reproducibility. Furthermore, hydrophobic compounds elute much faster with Purospher™ STAR Phenyl columns than with C-18 columns.
