Abstract (en)
[origin: WO2017037094A1] The invention relates to a device for electrochemical detection by amperometry of at least one electroactive species in a liquid medium. It comprises: a system for electrochemical measurement by amperometry (12); at least two work electrodes (3); at least one reference electrode (4); and at least one counter electrode (5); the work electrodes, the reference electrode and the counter electrode being connected to the electrochemical measurement system in order to allow electrochemical detection by amperometry of said species. The device is characterised in that each work electrode includes an electrically conductive mounting (14) made of doped diamond, having a surface portion covered by a metal catalyst that is different for each work electrode, said metal catalyst being in the form of separate contact pads (13) of nanometric size and being selected from gold, silver, rhodium, osmium, platinum, iridium, palladium, ruthenium and the alloys thereof.
