In this paper, we report a new electroanalytical technique we call snapshot voltammetry. This method combines the properties of bipolar electrodes with electrogenerated chemiluminescence (ECL) to provide a means for recording optical voltammograms in a single micrograph. In essence, the information in a snapshot voltammogram is contained in the spatial domain rather than in the time domain, which is the case for conventional voltammetry. The use of a triangle-shaped bipolar electrode stabilizes the interfacial potential difference along its length. Basic electrochemical parameters extracted from snapshot voltammograms are in good agreement with those obtained by conventional voltammetry. Although not explicitly demonstrated in this paper, this method offers the possibility of using arrays of bipolar electrodes to obtain numerous snapshot voltammograms simultaneously.
在本文中，我们报告了一种新的电分析技术，我们称之为快照伏安法。该方法结合了双极电极的特性和电致化学发光（ECL），为在单个显微照片中记录光学伏安图提供了一种手段。从本质上讲，快照伏安图中的信息包含在空间域中，而不是在传统伏安法的时间域中。使用三角形双极电极可沿其长度稳定界面电位差。从快照伏安图中提取的基本电化学参数与通过传统伏安法获得的参数吻合良好。尽管本文并未明确证明，但该方法提供了使用双极电极阵列同时获得多个快照伏安图的可能性。
