General description
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。

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
