Abstract
La presente invención proporciona un método y aparato para determinar la cantidad de varios materiales en una muestra líquida. Debido a que el aparato es particularmente flexible éste puede usarse repetidamente con muestras líquidas muy duras tal como agua de separador de gas de una refinería de petróleo. El aparato utiliza al menos un volumen y/o un método de análisis óptico independiente de la concentración para determinar al menos uno de: el pH, cantidad de cloruro, y/o cantidad de hierro en la muestra. La propiedad óptica puede ser colorimétrica, fluorescente o ambas, y resulta de adicionar colorantes, agentes formadores de complejo, compuestos inductores de turbidez, y otros reactivos que afectan ópticamente a la muestra. Debido a que las mediciones son de concentración y volumen independiente, éstas pueden ser realizadas continuamente, en forma rápida, y evitar el inconveniente de los procedimientos de arranque: y parada en los regímenes de medición de la técnica previa. El método además incluye utilizar una célula BDD para oxdar materiales (tal como compuestos sulfoxi) que pudieran de otra manera interferir con el análisis óptico y/o burbujear la muestra con gas.
