位于微盘电极中心的玻璃球的大小通过使用简单的电化学程序来确定，并且另外通过在电化学测量时对该玻璃球的显微测量来确认。在很宽的扫描速率范围内(0.002~1.5V S~(-1))，记录了裸电极和球心电极的循环伏安响应。然后，通过将实验伏安图与每个单独扫描速率的模拟进行比较来确定球体的大小。
The size of a glass sphere positioned in the center of a microdisk electrode is determined by using a simple electrochemical procedure and is confirmed, additionally, by a microscopical measurement of the sphere at the time of the electrochemical measurement. The cyclic voltammetric response of the naked electrode and of the electrode with the sphere positioned in its center is recorded over a wide range of scan rates (0.002-1.5 V s(-1)). The size of the sphere is then determined by comparison of the experimental voltammogram with simulations for each individual scan rate.
