合成了一种高度稳定的假固定相，并对其在胶束电动毛细管色谱（MECC）中的应用进行了评价。按照Durairaj等人的方法，10-十一烯酸钠被寡聚形成胶束状结构。这种结构的稳定性使其适用于含有相对高百分比有机改性剂的流动相，可以分离和检测常规胶束电动色谱难以分析的疏水分析物，如邻苯二甲酸烷基酯和多核芳烃（PAHs）。除了证明这种结构在分析疏水分析物中的实用性外，还研究了新相的电泳和色谱性质。
A highly stable pseudostationary phase has been synthesized and evaluated for use in micellar electrokinetic capillary chromatography (MECC). Sodium 10-undecylenate has been oligomerized to form a micelle-like structure following the procedure of Durairaj et al. [1].The stability of this structure renders it suitable for use with mobile phases containing relatively high percentages of organic modifiers, enabling the separation and detection of hydrophobic analytes such as alkyl phthalates and polynuclear aromatic hydrocarbons (PAHs) which are difficult to analyze by conventional micellar electrokinetic chromatography. In addition to demonstrating the utility of this structure for the analysis of hydrophobic analytes, the electrophoretic and chromatographic properties of the new phase have been investigated.
