Abstract

PROCEDIMIENTO PARA EL ANALISIS DIRECTO Y CONTINUO DE TRAZAS DE HIDRUROS GASEOSOS EN UN GAS VECTOR. CONSISTE EN LA SEPARACION CROMATOGRAFICA DE LOS GASES, SEGUIDA DEL TRATAMIENTO EN PRESENCIA DE OZONO Y ESTUDIO DE LOS ESPECTROS DE EMISION LUMINISCENTE, FILTRADOS OPTICAMENTE ENTRE 4950 Y 6500 A Y AMPLIFICADOS MEDIANTE UN TUBO FOTOMULTIPLICADOR CAPAZ DE TRABAJAR EN LA ZONA ESPECTRAL INDICADA. ESTE PROCEDIMIENTO TIENE APLICACIONES PARA EL ANALISIS DE ARSINA, FOSFINA, SILANO Y DIBORANO.
