Abstract

Disposición óptica de medición para determinar la radiación de transmisión y la radiación dispersa de una muestra líquida sometida a una radiación de medición, con un tubo capilar (1) para alojamiento de la muestra líquida; con una fuente de luz (2) para la emisión de la radiación de medición, en lo esencial en perpendicular al eje longitudinal (1¿) del tubo capilar (1); con un primer detector (4) para detectar la radiación de transmisión, el cual está situado en la zona del eje (3¿) de la radiación de medición; así como con un segundo detector (5) para detectar la radiación dispersa, colocado en la dirección del eje longitudinal (1¿) del tubo capilar (1) a una distancia (a) del primer detector (4), estando el primer detector (4) y el segundo detector (5) situados en lados diferentes de un plano (å), que contiene el eje longitudinal (1¿) del tubo capilar (1) y que está en perpendicular al eje (3¿) de la radiación de medición; caracterizada porque la disposición comprende un bloque de medición (10) con un taladro (9) para alojamiento del tubo capilar (1), y porque, entre una zona de acoplamiento (6) para la radiación de medición y una zona de desacoplamiento (7) para la radiación dispersa, está previsto por lo menos un elemento óptico de separación (13), que cubre una hendidura anular (14) de separación entre el tubo capilar (1) y el taladro (9).
