Abstract

Se proporciona un módulo de presentación (21) para presentar una muestra de fluido a un análisis de espectroscopia de plasma inducida por láser (LIBS). El módulo de presentación (21) comprende una entrada (22, 27) para admitir un flujo de muestra de fluido (25) de un flujo de proceso, una abertura de medición para cooperar con los dispositivos ópticos de medición (31, 32, 33, 34), y una superficie del estabilizador (26) que hace frente hacia la abertura de medición. La superficie del estabilizador (26) está adaptada para formar un flujo de muestra estabilizada a lo largo de la superficie del estabilizador de modo que la profundidad y la superficie exterior del flujo de muestra 25 se estabilizan, y la fluctuación de superficie y la variación de profundidad del flujo de suspensión de muestra estabilizada se reducen. Los pulsos de láser (29) se enfocan en la superficie exterior del flujo de muestra plana (25) para transformar por lo menos una parte de la muestra en un estado de un plasma, la exactitud y la característica de repetición de la medición LIBS se mejoran significativamente debido al flujo de muestra estabilizada.
