Application of an autoranging amplifier in the simultaneous determination of trace heavy metals by anodic stripping
1Department of Electrical Engineering, Ben-Gurion University of the Negev, Beer-Sheva, Israel.
Abstract:
An autoranging amplifier with a gain of 1-1000 is described, together with its possible application in anodic stripping voltammetry. The performance of the amplifier is demonstrated by differential-pulse anodic stripping voltammetric analysis of stored sea-water, in the subtractive mode with two working electrodes. It is suggested that the autoranging amplifier could save considerable analysis time by eliminating the need for trial runs for gain adjustments and by relieving the operator from the need to change the recorder scale during the analysis.
