A new electrochemical device, the scanning droplet cell, is presented. Small electrolyte droplets are positioned on the sample surface and enable a spatially resolved surface analysis or modification. The droplet is simply held by its surface tension and, therefore, no surface pretreatment is necessary. According to the conventional 3-electrode arrangement all common potentiostatic and galvanostatic techniques, e.g. impedance spectroscopy, cyclic voltammetry, or current transients of potentiostatic steps, are possible.
本文介绍了一种新型电化学装置——扫描液滴池。小的电解质液滴置于样品表面，可实现空间分辨的表面分析或修饰。液滴仅靠表面张力固定，因此无需进行表面预处理。根据传统的三电极配置，所有常见的恒电位和恒电流技术，如阻抗谱、循环伏安法或恒电位阶跃的电流瞬变等都是可行的。
