一般描述
由于溶质与键合相的芳香环及其离域电子发生相互作用，使Phenyl-Hexyl固定相具有独特的选择性。这种独特的芳香基选择性使其与C18和RP-酰胺固定相互补（正交）。Phenyl-Hexyl固定相也倾向于具有良好的形状选择性，这可能来自于溶质与平面环系统的多点相互作用。对于具有芳族吸电子基团（氟、硝基等）或具有离域杂环系统（如苯二氮类化合物）的溶质，通常具有更强的保留性和选择性。
应用
- 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 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
