Abstract
En su forma de realización más amplia, el presente método comprende el análisis de urea en un líquido, en la forma de sangre, otros fluidos corporales que contienen urea, un dializado o una combinación de los mismos, poniendo dicho líquido en contacto con una lengua electrónica que comprende por lo menos un electrodo de trabajo. Se aplica una secuencia de pulsos de tensión a los electrodos. Las amplitudes de pulso pueden ser diferentes para electrodos diferentes, y en forma apropiada las amplitudes se varían entre potenciales negativos y potenciales positivos. Reivindicación 7: Un sistema para analizar urea en un líquido, en la forma de sangre, otros fluidos corporales que contienen urea, un dializado o una combinación de los mismos, de acuerdo con el método de la reivindicación 1 caracterizado porque comprende: una unidad sensora voltamétrica que comprende por lo menos un electrodo de trabajo; un contraelectrodo; un potenciostato con un generador de pulsos programable; una unidad de procesamiento para el procesamiento matemático de datos voltamétricos utilizando un modelo basado en análisis multivariable.In its broadest embodiment, the present method comprises the analysis of urea in a liquid, in the form of blood, other body fluids containing urea, a dialysate or a combination thereof, putting said liquid in contact with a tongue electronics comprising at least one working electrode. A sequence of voltage pulses is applied to the electrodes. Pulse amplitudes may be different for different electrodes, and appropriately the amplitudes are varied between negative potentials and positive potentials. Claim 7: A system for analyzing urea in a liquid, in the form of blood, other body fluids containing urea, a dialysate or a combination thereof, according to the method of claim 1 characterized in that it comprises: a sensing unit voltammetric comprising at least one working electrode; a counter electrode; a potentiostat with a programmable pulse generator; a processing unit for the mathematical processing of voltammetric data using a model based on multivariable analysis.
