General description

The Phenyl-Hexyl phase has unique selectivity arising from solute interaction with the aromatic ring and its delocalized electrons. It is complementary (orthogonal) to both C18 and RP-Amide phases because of this unique aromaticity. The Phenyl-Hexyl phase also tend to exhibit good shape selectivity, which may originate from solute multipoint interaction with the planar ring system. More retention and selectivity will often be observed for solutes with aromatic electron-withdrawing groups (fluorine, nitro, etc.) or with a delocalized heterocyclic ring system such as the benzodiazepine compounds.

Ascentis® Express Phenyl Hexyl Columns for U/HPLC

Improve your reversed phase selectivity for polar aromatics and heterocyclic compounds with the Ascentis® Express Phenyl-Hexyl U/HPLC column.

Benefits of Ascentis Express Phenyl-Hexyl over Biphenyl for the Separation of Pain Management Opiates

Although both biphenyl and phenyl-hexyl phases can resolve these compounds, the former exhibits excellent peak shape and substantially less silanol-derived ion exchange activity.

The recent introduction of new stationary phases for liquid chromatography based on superficially porous particles, called core-shell or fused-core, dramatically improved the separation performances through very high efficiency, due mainly to reduced eddy diffusion. However, few studies have evaluated the
