Potentiometric stripping analysis automation.
A semi-automatic system for potentiometric stripping analysis (PSA) based on the use of a potentiostat, a pH-meter with RS232C interface, and a personal computer is described. The appropriate software developed allows automatic control of the pre-electrolysis time, data acquisition and manual or automatic data treatment. Several elements can be determined at ng/ml level.
