Abstract

La invención se refiere a un dispositivo para determinar una concentración de una sustancia química disuelta en un líquido, sustancia química ésta que absorbe luz (10) de una longitud de onda de absorción, en donde el dispositivo comprende al menos una cámara de flujo continuo (2) que tiene al menos una abertura de entrada (4), al menos una abertura de salida (6), y al menos una pared periférica (24), al menos un láser (8) para emitir luz (10) de la longitud de onda de absorción y al menos un detector (18) para detectar la luz emitida (10), en donde el láser (8) y el detector (18) se disponen de manera que la luz (10) emitida por el láser (8) se conduce a través de la cámara de flujo continuo (2) a lo largo de al menos dos rutas diferentes antes de que incida en el detector (18), y el dispositivo tiene dos láser (8) que emiten luz de diferentes longitudes de onda. La invención se refiere además a un método para producir una cámara de flujo continuo para un dispositivo de este tipo.
