摘要：

We describe cells of various geometries for electrochemical measurements in submicroliter volumes. Three microelectrodes are embedded in a fluoropolymer, and the drop of solution to be analyzed is placed on the three electrodes. In this paper we describe the effects of the geometry of the three electrodes. In particular, band and disk working electrodes are compared. Also, the effect of spacing of the electrodes is explored. In order to achieve analysis of very small volumes the electrodes must be only slightly separated. However, diffusion of products from one electrode to another may affect the voltammograms.
