Derived or pulse voltammetry
Voltammetry on solid electrode

The refinement of voltammetric techniques to improve their performance in chemical analysis occurs on two levels: improving selectivity, on the one hand, and lowering the detection limit, on the other.

• With regard to selectivity, it is now well known that careful manipulation of solution effects (acidity, complex formation, precipitation, etc.) allows chemical action to influence both redox potentials and diffusion effects, thereby achieving better separation of compounds [P 2 127] .
