电化学溶出分析（ESA）是一种用于测定金属阳离子、无机离子、有机化合物和生物分子的痕量电分析技术。它基于目标分析物或目标化合物在合适的工作电极上的预浓缩步骤。接下来是使用电分析技术剥离积累的分析物的步骤。 ESA 的优点包括高灵敏度和低检测限、多分析物能力、仪器和耗材成本低、功耗要求低、现场分析潜力、形态形成能力和间接生物传感范围。本入门书涵盖了 ESA 的基本方面，并讨论了预浓缩和剥离的方法、仪器、工作电极和传感器的类型、方法优化指南、典型应用、数据解释和干扰以及方法限制和解决方法。最后，重点介绍了欧空局的当前趋势和未来前景。
Electrochemical stripping analysis (ESA) is a trace electroanalytical technique for the determination of metal cations, inorganic ions, organic compounds and biomolecules. It is based on a pre-concentration step of the target analyte(s), or a compound of the target, on a suitable working electrode. This is followed by a stripping step of the accumulated analyte using an electroanalytical technique. Advantages of ESA include high sensitivity and low limits of detection, multi-analyte capability, low cost of instrumentation and consumables, low power requirements, potential for on-site analysis, speciation capability and scope for indirect biosensing. This Primer covers fundamental aspects of ESA and discusses methods of pre-concentration and stripping, instrumentation, types of working electrodes and sensors, guidelines for method optimization, typical applications, data interpretation and interferences, and method limitations and workarounds. Finally, the current trends and future prospects of ESA are highlighted.
