Fundamental understanding of electrochemistry in nonaqueous electrolytes is important for applications like nonaqueous batteries, electroorganic synthesis, CO₂ reduction, or metal deposition. Studies on electrode stability contribute to our fundamental understanding and are essential for the evaluation of the overall performance of electrochemical systems. With this work we introduce a tool to this field aiming to particularly investigate dissolution of different electrode materials qualitatively and quantitatively in water-free, organic media. The new approach consists of an electroanalytical flow cell with scanning capability on-line coupled to an inductively coupled plasma mass spectrometer, all together optimized to harsh organic environments. As a case study to demonstrate the strength of the method, we have chosen platinum as working electrode. We unveil its dissolution behavior in methanol-based organic electrolytes for the first time under controlled atmosphere (glovebox), and demonstrate differences in dissolution mechanism compared to aqueous electrolytes.

对非水电解质中电化学的基本理解对于非水电池，有机合成，CO ₂等应用非常重要还原或金属沉积。电极稳定性的研究有助于我们的基本理解，对于评估电化学系统的整体性能至关重要。通过这项工作，我们为该领域引入了一种工具，旨在专门研究定性和定量地分析不同电极材料在无水有机介质中的溶解度。新方法包括一个电分析流通池，该池具有在线扫描功能，并与感应耦合等离子体质谱仪在线耦合，所有这些都针对恶劣的有机环境进行了优化。为了证明该方法的强度，我们选择了铂作为工作电极。我们首次在受控气氛下（手套箱）揭示了其在甲醇基有机电解质中的溶解行为，
