Abstract

La presente invención se refiere a un método para la medición por calibración de un solo punto de cuando menos una primera y una segunda especie en una solución, que emplea cuando menos un primero, un segundo y un tercer sensores, en donde el primer sensor es sensible a la primera y segunda especies, el segundo sensor es sensible a la primera especie y el tercer sensor es sensible a la segunda especie, el método está caracterizado porque comprende las etapas de: a) poner en contacto los sensores con una solución que contiene la primera y la segunda especies, b) obtener una primera y una segunda señales, la primera señal es la diferencia entre el primero y el segundo sensores y la segunda señal es la diferencia entre el primero y el tercer sensores, c) transportar la primera y la segunda señales hasta un procesador de señal, d) poner en contacto los sensores con una segunda solución que contiene cantidades conocidas de la primera y la segunda especies y obtener una tercera y una cuarta señales desde el primero y segundo senores y el primero y el tercer sensores, respectivamente, e) transportar la tercera y la cuarta señales a un procesador de señales, f) establecer las constantes algebráicas de la tercera y cuarta señales, g) hacer entrar las constantes dentro de un dispositivo de cálculo que determina la concentración de la primera y la segunda especies.
