Abstract

Sensores que pueden medir el caudal de un fluido que pasa sobre los electrodos de los mismos. En estos sensores, un electrodo, designado el electrodo medidor de caudal, se usa en conjunción con los electrodos convencionales, por ejemplo, el electrodo de trabajo, el electrodo de referencia, y el contraelectrodo, para determinar el caudal del fluido. En un aspecto, la presente provee un sensor para medir la concentración de un analito en una muestra de fluido cuando la muestra fluye constantemente sobre los electrodos del sensor, especialmente cuando el caudal de la muestra es relativamente bajo. En otro aspecto, la presente provee un método para medir la concentración de un analito en una muestra de fluido, cuando el caudal de la muestra varía durante el plazo durante el cual el sensor está en posición. En una realización preferida, el sensor utiliza cuatro electrodos, a saber, un electrodo de trabajo, un electrodo de referencia, un contraelectrodo, y un electrodo medidor de caudal. Como alternativa, un único electrodo que desempena tanto la función del electrodo de referencia como la función del contraelectrodo puede reemplazar al electrodo de referencia y el contraelectrodo. Además, se puede usar un electrodo falso o en blanco para compensar las interferencias de especies electroquímicamente activas. El / los reactivos / s específicos para el analito de interés deben ser depositados sobre el electrodo de trabajo.
