Descrição

Descrição geral

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.

Aplicação

• A fully automated and fast method using direct sample injection combined with fused-core column on-line SPE-HPLC for determination of ochratoxin A and citrinin in lager beers.: This study by Lhotská et al. explores the application of a fused-core column combined with on-line SPE-HPLC for rapid and automated analysis of ochratoxin A and citrinin in lager beers. The Ascentis^® Express Phenyl-Hexyl column demonstrates high efficiency and selectivity, significantly improving the throughput and sensitivity of the analysis (Lhotská et al., 2016).
