摘要：

A fully automated setup for impedance measurements at the dropping mercury electrode (DME) is described. It is based on the Solartron 1250 frequency response analyzer, and it incorporates an infrared drop-fall detector. Synchronization with the DME as well as calibration procedures are considered in some detail. Experiments on dummy and electrolytic cells, with and without electroactive species, were performed, and data are compared with earlier results on the same systems.
