Abstract

ESTE DISPOSITIVO CAPTADOR AMPEROMETRICO COMPRENDE UN CAPTADOR (21) QUE TIENE UNA ESTRUCTURA PLANAR, OBTENIDA MEDIANTE TECNICAS FOTOLITOGRAFICAS, Y UN CIRCUITO (22) PARA MEDIR LA INTENSIDAD DE LA CORRIENTE ELECTROQUIMICA PRODUCIDA POR EL CAPTADOR (21). LA ESTRUCTURA PLANAR LLEVA UN SUSTRATO AISLANTE (23 A 25) Y UN JUEGO DE ELECTRODOS FORMADO POR UN ELECTRODO DE TRABAJO (29), UN CONTRAELECTRODO (30) Y UN ELECTRODO DE REFERENCIA (31). UNA MEMBRANA DE DIFUSION (32) SE DEPOSITA SOBRE EL ELECTRODO DE TRABAJO (30). SE DISPONE DE MEDIOS DE CONEXION (26) PARA CONECTAR LOS ELECTRODOS (29, 30, 31) AL CIRCUITO DE MEDIDA (22). CONFORME A LA INVENCION, LA PARTE CONDUCTORA ACTIVA DEL ELECTRODO DE TRABAJO (29), SITUADA EN LA SUPERFICIE DEL SUSTRATO (23), ESTA TOTALMENTE CUBIERTA POR LA MEMBRANA DE DIFUSION (32), QUE EXCEDE DE ESTE ELECTRODO (29) POR TODA SU ZONA PERIFERICA, MIENTRAS QUE ESTA MEMBRANA ESTA TOTALMENTE EXPUESTA PARA QUE, EN EL CURSO DEL FUNCIONAMIENTO DEL DISPOSITIVO (20), SE PONGA EN CONTACTO CON EL FLUIDO A ANALIZAR POR TODA SU SUPERFICIE. APLICACION A LA MEDICION DEL CONTENIDO DE UNA SUSTANCIA OXIRREDUCTIBLE EN UN FLUIDO, EN ESPECIAL CLORO, EN EL AGUA POTABLE.
