Abstract

La presente invención se relaciona con métodos que pueden usarse para calibrar automáticamente un instrumento de medición de fluorescencia capaz de medir continuamente la concentración de la dureza en agua de proceso. El método de calibración se usa para compensar el desplazamiento de instrumento y equipo, los cambios de condiciones operacionales y la contaminación de reactivos y estándares de calibración. La calibración del instrumento de medición de la fluorescencia usando el presente método de calibración mejora la exactitud y la capacidad de repetición para las mediciones de la concentración de dureza subsecuentes.
