Abstract:
1. A flow cell assembly for use in a liquid sample analyzer, the liquid sample analyzer including a radiation source, a sensing device and a liquid sample source to supply a liquid sample, the flow cell assembly comprising: a joint member including an axially extending alignment bore, the alignment bore including a waveguide receiving bore section and an optical fiber termination receiving bore section; a liquid core waveguide mounted in the waveguide receiving bore section, the liquid core waveguide defining a waveguide bore; and an optical fiber assembly including an optical fiber and a ferrule mounted on an end of the optical fiber, wherein the end of the optical fiber and the ferrule are mounted in the optical fiber termination receiving bore section, the optical fiber having an exposed optical fiber end face adjacent the ferrule; wherein the alignment bore radially aligns the liquid core waveguide with the ferrule and thereby radially aligns the optical fiber end face with the waveguide bore; and wherein the optical fiber is operative to transmit radiation from the radiation source to the waveguide bore, which radiation is transmitted through the waveguide bore and the liquid sample therein to the sensing device.
