Abstract:
A flow cell for containing a fluid sample and exposing the fluid sample to radiation for analysis, the flow cell comprising:a flow cell body having a through-aperture with an inner surface, and having a first end and a second end, said flow cell body having a plastic composition allowing said flow cell body to be molded around a light guiding member;a light guiding member fixed to said inner surface of said flow cell body by molding and having a wetted surface defining a chamber for receiving one or more fluids, said wetted surface comprised of a amorphous fluoropolymer having a refractive index less than the refractive index of said fluid sample to direct light impinging on said wetted surface to reflect into said fluid sample;a first end interface disposed proximate to said end of said flow cell body and a second end interface disposed proximate to said second end of said flow cell body, each of said first and second end interface comprising a light transmitting member; andan inlet and an outlet fluid transmitting member disposed in one of said flow cell body and light guiding member or said first or second end interface.
