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。

Application


  • 一种采用直接进样结合熔融核柱在线SPE-HPLC的全自动快速方法，用于测定拉格啤酒中的赭曲霉毒素A和橘霉素。展示了Ascentis ®Express Phenyl-Hexyl2.7μ m HPLC柱在自动检测饮料中污染物方面的稳健性。本研究彰显了高通量分析用色谱柱的能力，这对食品行业的质量控制至关重要，确保了安全性并符合监管标准（Lhotská et al., 2016）。

  • 核壳颗粒柱在顺序注射色谱法酚酸测定中的优势：这项研究强调了Ascentis ®Express Phenyl-Hexyl柱在分析复杂酚类化合物方面的效率，说明了其在环境和制药应用中的优越性能。柱的设计增强了分离能力，这对各种样品中的酚类分析至关重要（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
