Applications of Voltammetry:
All these methods could be applied quantitatively for the analysis of huge variety of samples (steels, environmental samples, clinical samples etc). The choice of a particular technique will depend on the analyte's characteristics, expected concentration and other constituents present and location of the sample.
Pulse polarography is better for analyzing a huge range of inorganic/organic anal ytes. Although in the case of stripping methods the analyte is to be preconcentrated at the electrode surface. Additionally the concentration of the analyte in the sample, the accuracy and precision needed will decide the technique to be selected.
The analysis of a sample component is quite easy and any of the methods could be used and from the linear relationship among the current and concentration, the unknown concentration within the sample could be acquired. In case of samples holding more than one analyte; if the elements behave independently, the analysis will be a simple addition of the respective individual separation voltammograms. Therefore if the id or ip is sufficient they could be determined independently as if they were only single elements.
