5. Conclusion

Polarographic analysis techniques are tried-and-tested and can be used for a wide range of applications in all fields where analytical requirements include understanding phenomena, determining thermodynamic quantities, quality control, monitoring substances of interest in manufacturing processes, effluent and pollution control, toxicological and medical studies, understanding chemical, biochemical and biological processes in the living world, fraud and doping control, and environmental quality. All concentration levels can be reached, from ultratrace to major compounds, using the polarographic technique best suited to the intended application.
