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.

With LiChroCART® cartridges the user works with re-usable endfittings which fit different cartridge lengths. 
Since these cartridge holders may remain in the system and the capillary connections do not need to be detached, 
the cartridges may be changed within the shortest possible time. Changing a separation cartridge from a length 
of 125 to 250 mm and back presents no problems. Furthermore, the adaptation of internal diameter (3 mm or 2 mm) 
to the analysis problem is possible within a few minutes. The endfittings are designed to allow the cartridges to be 
hand-sealed at normal working pressures of 150 to 200 bar without the need for any tools. Only at higher pressures 
may further tightening with a wrench become necessary.
