Abstract

Appareil électrochimique d'analyse à faible empoisonnement d'électrodes et courant perturbateur. Une chambre de réaction avec entrée et sortie est en contact avec des électrodes protégées par une membrane semi-perméable à grandeurs de pores comprises dans des intervalles définis pour ne laisser diffuser que des molécules de grosseur faible choisie. Le réglage du débit en fonction des grandeurs de pores permet d'éliminer les espèces toxiques à macromolécule et de réduire l'accès aux surfaces actives d'électrodes des espèces perturbatrices à petites molécules. Applicable notamment à l'analyse de liquides biologiques.
