Abstract
SE OFRECE UN PROCEDIMIENTO PAARA EL ANALISIS DE ELEMENTOS MEDIANTE EL ANALISIS ESPECTRAL DE EMISION INDUCIA POR LASER DE UN CALDO METALICO EN SU SUPERFICIE EN UNA PERFORACION REALIZADA EN UN RECIPIENTE DE FUNDICION (1). LA PERFORACION VA DOTADA DE UN TUBO (4) QUE ESTA CERRADO EXTERNAMENTE CON UNA VENTANA DE CUARZO (6). POR UN CODO (5) LATERAL AL TUBO FLUYE DENTRO DE LA PERFORACION UN GAS INERTE A UNA TEMPERATURA DE MAS DE 300 C . EL TUBO (4) ESTA CONECTADO CON UNA CARCASA (7) QUE VA ACOPLADA A UN ESPECTROMETRO (15) A TRAVES DE UN TRANSMISOR DE ONDAS DE LUZ (14), LA LUZ LASER DE UN LASER (8) QUE SE ENCUENTRA DENTRO DE LA CARCASA SE ENFOCA, MEDIANTE LENTES AJUSTABLES (9) Y UN ESPEJO (10), SOBRE LA SUPERFICIE DEL METAL (12) Y PRODUCE EN ELLA UN PLASMA (11). LA LUZ PLASMA EMITIDA POR LA SUPERFICIE DEL METAL SE ACOPLA CON UN SISTEMA DE LENTES (13A, 13B) AJUSTABLES DENTRO DEL TRANSISTOR DE ONDAS DE LUZ (14) Y SE CONDUCE AL ESPECTROMETRO (15.
