This report describes the use of differential pulse stripping analysis with thin film electrodes for the determination of lead and cadmium in a variety of samples. Instrumental and chemical parameters have been thoroughly investigated and optimized for the direct determination of these elements in natural waters, blood, blood plasma, and urine. The results indicate that reliable analyses are obtained on samples as small as a few microliters under conditions which are more sensitive than linear scan stripping techniques by factors ranging from 4 to 20 or more.
