Abstract

L'invention concerne une analyse chimique polarimétrique à guide d'onde optique distribué. La surveillance en temps réel d'un procédé de séparation d'un fluide dans une colonne capillaire est assurée à l'aide d'un capteur distribué comprenant un guide d'onde optique biréfringent placé entre deux polariseurs. Le guide d'onde optique comprend un canal longitudinal défini par une surface de canal dans sa gaine et adapté pour recevoir le fluide de sorte qu'il se déplace dans ledit canal longitudinal. Le canal longitudinal est positionné par rapport au cur de sorte que l'absorption en surface de canal du fluide se déplaçant dans la direction longitudinale entraîne une variation locale de l'orientation des axes de polarisation du guide d'onde optique. Le mode de réalisation proposé peut être utilisé pour surveiller la vitesse des composants séparés de long du canal.
