Puget Sound, Wash

The automated system is controlled by a specially designed programmer which controls the potentiostat, the recorder, two peristaltic pumps, and five solenoid-operated valves which alternately circulate a mercuric nitrate solution, a seawater sample, or a standard solution through the electrode assemblage. Automated analyses for copper, zinc, cadmium, and lead were made on the pier of the Scripps Institution of Oceanography, San Diego, Calif., and aboard ship in Puget Sound, Wash. This report describes the automated system, discusses the performance of the electrode imder continued use, and presents the results obtained in the field.
