Abstract
The invention relates to distributed optical waveguide polarimetric chemical analysis. Real-time monitoring of a separation process of a fluid in a capillary column is provided using a distributed sensor comprising a birefringent optical waveguide placed between two polarizers. The optical waveguide has a longitudinal channel defined by a channel surface in its cladding and adapted to receive the fluid such that it travels in said longitudinal channel. The longitudinal channel is positioned with respect to the core such that channel surface absorption of the fluid traveling in the longitudinal channel causes a local variation of the orientation of the polarization axes of the optical waveguide. The proposed embodiment can be used for monitoring the velocity of the separated components along the channel.
