Abstract

Un detector de metales alcalinos del tipo de ionización que comprende un dispositivo ionizador térmico, un primer dispositivo de circuito para mantener la temperatura de dicho dispositivo ionizador térmico a una temperatura capaz de ionizar átomos y compuestos de metal alcalino presentes en un gas portador, un electrodo separado de dicho dispositivo ionizador térmico, y un segundo dispositivo de circuito para establecer una corriente de iones positivos de metal alcalino desde dicho dispositivo ionizador térmico a dicho electrodo, siendo dicha corriente de iones positivos de metal alcalino, indicativa de la concentración de dicho metal alcalino presente en dicho gas portador, caracterizado dicho detector porque dicho dispositivo ionizador térmico comprende un electrodo que posee un revestimiento óxido protector en respuesta a los átomos y compuestos de metal alcalino de choque produciendo dichos iones positivos de metal alcalino mediante ionización superficial térmica de los átomos y compuestos de metal alcalino.
