Since surfactants reduce the interfacial tension of immiscible liquids by forming micelles through hydrophobic and hydrophilic groups in their structure, they are frequently used in different fields of analytical chemistry. The use of surfactants in analytical techniques continues to increase from past to present. They are used in chromatography to improve separation efficiency and reduce the amount of organic solvent. In electrochemical techniques, they have important functions such as increasing the selectivity and sensitivity of the sensor in the supporting electrolyte or as an electrode modifying agent. The use of surfactants in these techniques, as well as in capillary electrophoresis and sample preparation, draws attention. This review summarizes the recent applications of surfactants in these analytical techniques, along with their primary usage in chromatography, capillary electrophoresis, and electrochemical analysis. Moreover, this review also describes the structural properties of surfactants and the advantages of their use in these analytical techniques.

由于表面活性剂通过其结构中的疏水和亲水基团形成胶束来降低不混溶液体的界面张力，因此它们经常用于不同的分析化学领域。从过去到现在，表面活性剂在分析技术中的使用不断增加。它们用于色谱中以提高分离效率并减少有机溶剂的用量。在电化学技术中，它们具有重要的功能，例如提高传感器在支持电解质中的选择性和灵敏度或作为电极改性剂。在这些技术以及毛细管电泳和样品制备中使用表面活性剂引起了人们的注意。本综述总结了表面活性剂在这些分析技术中的最新应用，以及它们在色谱、毛细管电泳和电化学分析中的主要用途。此外，这篇综述还描述了表面活性剂的结构特性及其在这些分析技术中的使用优势。
