These practical kits allow students with or without electrochemical experience to complement their academic
programs by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field.

Stripping analysis is widely used in metal analysis. This technique incorporates an electrolytic pre-concentration step before stripping performed by a voltammetry technique. Cyclic Voltammetry allows to characterize and define the oxidation and reducction processes on screen-printed electrodes, as well as the possibility of applying this electrolytic pre-concentration step. Square Wave Voltammetry is used for an enhancement of the electrochemical signal once frequency, amplitude, potential and time of deposition are optimized. Analytical characteristics are determined and  measurement of copper in tap water can be easily carried out.

The kit contains:

• The professor outline
• The student outline

• A box of suitable screen-printed electrodes (50 units)

• The needed analyte
