Popis

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.

Application

• 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 presents a rapid, automated method for the detection of mycotoxins in beer using high-performance liquid chromatography. The use of the Ascentis^® Express Phenyl-Hexyl column enables efficient and effective sample processing, demonstrating its applicability in food safety and quality control (Lhotska et al., 2016).


• Advantages of core-shell particle columns in Sequential Injection Chromatography for determination of phenolic acids.: This paper explores the benefits of using core-shell particle technology, including Ascentis^® Express Phenyl-Hexyl columns, in the analysis of phenolic acids. The study highlights the columns′ enhanced performance and efficiency, making them valuable for chemical analysis in environmental and food samples (Chocholous et al., 2013).
