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


  • 一种使用直接进样结合熔融芯柱在线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和桔霉素。: 本研究提出了一种使用高效液相色谱法快速、自动化检测啤酒中霉菌毒素的方法。Ascentis® Express Phenyl-Hexyl柱的使用实现了高效的样品处理，证明了其在食品安全和质量控制中的适用性（Lhotska et al., 2016）。

  • 核壳颗粒柱在顺序注射色谱法酚酸测定中的优势。: 本论文探讨了使用核壳颗粒技术（包括Ascentis ®Express Phenyl Hexyl柱）分析酚酸的益处。该研究重点介绍了这些柱提高的性能和效率，这一特性使其在环境和食品样品的化学分析中具有重要价值（Chocholous 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
