Abstract

SE PROPORCIONAN UN METODO Y APARATO PARA DETERMINAR LA CONCENTRACION DE UN ANALITO EN UNA MUESTRA DE ANALISIS DE FLUIDO, APLICANDO LA MUESTRA DE ANALISIS DE FLUIDO A LA SUPERFICIE DE UN ELECTRODO MOTOR EL CUAL ESTA ELECTROQUIMICAMENTE CONECTADO A UN ELECTRODO DE REFERENCIA CUYA SUPERFICIE SOPORTA UNA COMPOSICION QUE INCLUYE UNA ENZIMA ESPECIFICA PARA EL ANALITO. UN MEDIADOR ES REDUCIDO EN RESPUESTA A UNA REACCION ENTRE EL ANALITO Y LA ENZIMA. SE APLICA UN POTENCIAL DE OXIDACION ENTRE LOS ELECTRODOS PARA DEVOLVER AL MENOS UNA PORCION DEL MEDIADOR A SU FORMA OXIDADA ANTES DE DETERMINAR LA CONCENTRACION DEL ANALITO PARA DE ESTA FORMA INCREMENTAR LA EXACTITUD DE LA DETERMINACION DEL ANALITO. DESPUES DE ESTE POTENCIAL APLICADO INICIALMENTE, EL CIRCUITO ES CONMUTADO A UN CIRCUITO ABIERTO O A UN POTENCIAL QUE REDUCE SUSTANCIALMENTE LA CORRIENTE PARA MINIMIZAR LA PROPORCION DE POTENCIAL ELECTROQUIMICO DEL ELECTRODO MOTOR. UN SEGUNDO POTENCIAL QUE ES APLICADO ENTRE LOS ELECTRODOS Y LA CORRIENTE GENERADA EN LA MUESTRA DE ANALISIS DE FLUIDO SE MIDE PARA DETERMINAR LA CONCENTRACION DE ANALITO. OPCIONALMENTE LA EXACTITUD DE LA DETERMINACION DEL ANALITO ES ADEMAS INCREMENTADA ALGORITMICAMENTE.
