Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA EL ANALISIS DE SOLUCIONES DE COLORANTES QUE EVENTUALMENTE CONTIENEN PRODUCTOS SOLIDOS, DE SUS PRODUCTOS DE PARTIDA Y PRODUCTOS INTERMEDIOS, MEDIANTE MEDIDAS OPTICAS Y/O ESPECTROSCOPICAS, QUE ESTA CARACTERIZADO POR EL HECHO DE QUE COMO SISTEMA SENSOR SE EMPLEA UN MONTAJE QUE SE BASA EN EL PRINCIPIO DE LA REFLEXION TOTAL DEBILITADA. LAS VENTAJAS DE ESTE PROCEDIMIENTO SON DE QUE SE PUEDEN ANALIZAR TAMBIEN SOLUCIONES MUY CONCENTRADAS Y FUERTEMENTE COLOREADAS SIN TENER QUE HACER DILUCIONES PREVIAS O, TAMBIEN DISPERSIONES DE COLORANTES SIN TENER QUE SEPARAR LAS PARTICULAS SOLIDAS.
