Peak area as instrumental datum for determining the concentration of metals in solution instead of peak height is proposed for analytical voltammetric determinations. In the case of species present at ultra‐trace concentration level or having low reversibility degree electrodic processes, the employment of peak area permits to achieve limits of detection lower even more of one order of magnitude. The present work shows the possibility of determining, at ultratrace level concentration, mercury(II) by differential pulse anodic stripping voltammetry (DPASV).
