The analysis of peaks such as in electrochemical or chromatographic measurements can be challenging as large volumes of data are involved, and its manual processing is time-consuming and inefficient. Herein, we describe a simple approach for the identification and area calculation of peaks, and specifically electrochemical peaks, with MATLAB. This approach allows a more convenient and efficient analysis of experimental results with a deviation of less than 10% from the methods used today. Finally, we demonstrate how the proposed method can be implemented for the analysis of the electrochemical oxidation of gold nanoparticles adsorbed on a solid electrode by linear sweep voltammetry.
