Phenyl 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.

The new Purospher® STAR Phenyl columns are based on 
high-purity 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.
