本文综述了用于毛细管电色谱分离的固定相的种类。目前，约70%的报道的CEC研究利用为液相色谱设计的C18固定相，但是越来越多的新材料（例如，离子交换相、溶胶-凝胶方法、有机聚合物连续床）正在开发中用于CEC。新的方面，这些不同的材料进行了讨论，包括促进电渗流，相选择性和碱性溶质的活性的能力。此外，新的柱设计（聚合物连续床和硅溶胶凝胶整料）进行了说明。
This review summarizes the variety of stationary phases that have been employed for capillary electrochromatography (CEC) separations. Currently, about 70% of reported CEC research utilizes C18stationary phases designed for liquid chromatography, but an increasing number of new materials (e.g., ion-exchange phases, sol–gel approaches, organic polymer continuous beds) are under development for use in CEC. Novel aspects of these different materials are discussed including the ability to promote electroosmotic flow, phase selectivity and activity for basic solutes. In addition, new column designs (polymer continuous beds and silica–sol–gel monoliths) are described.
