| Abstract: | The use of a solid electrode in routine analytical work is proposed as a good alternative for electroanalytical detection.
The performance of the electrode for oxidative voltammetry was studied for the model compound, catechol. Some theoretical
aspects of the preparation and features of the PVC-graphite composite electrode are shown. A protocol has been described for
its construction and general advice for the appropriate use. Quality control activities were designed to check the performance
of the electrode.
