Abstract
UN METODO Y APARATO PARA EL ANALISIS ESPECTROFOTOMETRICO DE UN MATERIAL EN POLVO MEDIANTE MEDICIONES DE REFLECTANCIA DE UN HAZ CUASI INFRARROJO QUE TIENE UNA CELULA DE MUESTRA (2) DENTRO DE LA CUAL EL POLVO (20A) SE COMPRIME ENTRE UNA PLANCHA DE MUELLE (13) Y UNA VENTANA (8) A UNA DENSIDAD PREDETERMINADA. EL ANALISIS ESPECTROFOTOMETRICO SE EFECTUA EN EL POLVO (20A) A TRAVES DE LA VENTANA (8) MEDIANTE EL ESCANEO CON UN HAZ INFRARROJO SOBRE UN AREA DEL POLVO (20A) QUE CUANDO SE MULTIPLICA POR LA DENSIDAD DEL POLVO Y LA PROFUNDIDAD DE PENETRACION DEL HAZ ES CONSISTENTE CON UN PESO DE DOSIFICACION PREDETERINADO DE MANERA QUE EL POLVO PUEDA SER MARCADO.
