Abstract

LA INVENCION SE REFIERE A UN METODO PARA EL ANALISIS CUANTITATIVO DE UNO O MAS ELEMENTOS EN UN BAÑO DE METAL FUNDIDO. SE ENFOCA LUZ DE UNA O MAS FUENTES DE LUZ CONTRA LA SUPERFICIE DEL BAÑO DE METAL FUNDIDO, Y SE REFLEJA DESDE DICHA SUPERFICIE A UN MONOCROMADOR O UN POLICROMADOR CONECTADO A DETECTORES PARA DETECTAR LUZ ABSORBIDA EN UNA CAPA DE GAS ASOCIADA CON EL METAL FUNDIDO CON UNA LONGITUD O LONGITUDES DE ONDA QUE SE CORRESPONDEN CON LOS ELEMENTOS A ANALIZAR. LAS SEÑALES DE ABSORCION SON PROPORCIONALES A LA DENSIDAD DE ATOMO O MOLECULAR DE LOS COMPONENTES A ANALIZAR, Y A UNA FUNCION DEL GROSOR DE LA CAPA DE GAS Y LA CONCENTRACION DE LOS ELEMENTOS EN EL BAÑO DE METAL FUNDIDO. LA CONCENTRACION DE LOS ELEMENTOS A ANALIZAR ES LA RELACION BASADA O CONOCIDA ENTRE LA SEÑAL DE ABSORCION, EL GROSOR DE LA CAPA DE GAS Y LA TEMPERATURA DEL BAÑO DE METAL FUNDIDO.
