Abstract : Studies of the current-voltage relationship, and of the effect of concentration of electrolyzable substances as well as of mercury flow rate on the limiting current were made on an analogue of the polarographic cell in which the dropping mercury electrode is replaced by an electrode which consists of mercury flowing through a channel in a Teflon block. The limiting current is directly proportional to the concentration of the reducible species and to the mercury flow rate. The precision of the results is poor, apparently as a result of irregular variations in the behavior of the electrode surface. Studies of the results obtained for various empirical modifications of the channel configuration indicate that it will be possible to improve the extent of reproducibility of the results. (Author)
