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: Demonstrates the robustness of the Ascentis® Express Phenyl-Hexyl, 2.7 μm HPLC column in automating the detection of contaminants in beverages. This study showcases the column′s capacity for high throughput analysis, essential for quality control in the food industry, ensuring safety and compliance with regulatory standards (Lhotská et al., 2016).
- Advantages of core-shell particle columns in Sequential Injection Chromatography for determination of phenolic acids: This research highlights the efficiency of the Ascentis® Express Phenyl-Hexyl column in analyzing complex phenolic compounds, illustrating its superior performance in environmental and pharmaceutical applications. The column′s design enables enhanced separation capabilities, crucial for accurate phenolic profiling in various samples (Chocholouš et al., 2013).

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

On-line sample pretreatment (clean-up and analyte preconcentration) is for the first time coupled to sequential injection chromatography. The approach combines anion-exchange solid-phase extraction and the highly effective pentafluorophenylpropyl (F5) fused-core particle column for separation of eight sulfonamide antibiotics with similar
