Abstract
La présence dun analyte sélectionné dans un échantillon est évaluée par un procédé électrochimique au moyen dun appareil de type à pile à conduction. Une différence de potentiel ou un courant est produit entre les deux électrodes de la pile suffisant pour provoquer loxydation ou la réduction de l'analyte ou dun médiateur dans un système de détection-réduction (redox) danalyte, formant ainsi un gradient de potentiel chimique de l'analyte ou du médiateur entre les deux électrodes. Après l'établissement du gradient, la différence de potentiel ou le courant appliqué est discontinué et un signal indépendant de l'analyte est obtenu de la relaxation du gradient de potentiel chimique. Le signal indépendant de l'analyte est utilisé pour corriger le signal indépendant de l'analyte obtenu pendant lapplication du potentiel ou du courant. La correction permet une mesure améliorée de la concentration danalyte grâce à la correction adaptée au dispositif et aux facteurs propres au test comme le transport (mobilité) de l'analyte ou du médiateur, la surface d'électrode efficace et l'espacement des électrodes (et par conséquent, un volume représentatif), sans nécessiter des valeurs d'étalonnage séparées. Lanalyse peut être exécutée au moyen de bandes de test jetables dans un appareil de mesure portatif, par exemple pour les tests de glucose.
