Abstract:
A flow cell (250) for a fluorescence spectrometer includes a flow channel (254) to receive a flow of a liquid sample, an excitation light entrance window to receive excitation light from a light source, and an emission light exit window to transmit fluorescent emission light from the liquid sample in the flow channel from the flow cell. The excitation light entrance window and/or emission light exit window includes a waveguide including: a waveguide core (261, 262) formed of a core material; and a cladding medium (274) surrounding a portion of the waveguide core (261, 262), wherein the cladding medium (274) has a refractive index less than the refractive index of the core material. The waveguide defines a portion of the flow channel (254). At least one mirror (270, 272) integral with the flow cell body is positioned to reflect excitation light that has passed through the liquid sample in the flow channel (254) back into the liquid sample and/or to reflect emission light emitted from the liquid sample toward the emission light exit window. The excitation light entrance window is spaced a first distance from the flow channel and the emission light exit window is spaced a second distance from the flow channel, whereby the second distance is less than the first distance.
Abstract:
A technique facilitates analysis of constituents in leaching operations by utilizing light energy and fiber optic transmission of light during the leaching operations. The light is used in situ in combination with a flow cell to measure desired constituents, e.g. copper, in a fluid flow stream. Additionally, the data obtained via the flow cell may be provided to a data processing system which may be used to automatically provide information, e.g. constituent concentration, within the flow stream. In many applications, the in situ fiber-optic transmission system and flow cell may be used in combination with the data processing system to provide real time information on the flow stream.

Abstract:
A clam-shell luminometer that, when closed, completely encloses an assay reaction mixture-containing reaction vessel and some portion of a reaction carousel or ring. The luminometer includes first and second portions that are coupled to each other, a photomultiplier tube, and plural fiber optic bundles that are optically coupled to the photomultiplier tube. First ends of the fiber optic bundles are disposed adjacent to the reaction vessel in the second portion so that the fiber optic bundles completely surround the perimeter or periphery of the reaction vessel.

Abstract:
An apparatus for detecting spectra in light emanating from chemical or biochemical reactions occurring in at least one reaction vessel (3) of a plurality of reaction vessels is disclosed. Each reaction vessel (3) has a receptacle portion having an emitting area from which light can emanate. The apparatus may include a masking element (5) having an array of apertures (6) through which light from each reaction vessel (3) can escape. A plurality of light waveguides (7) are arranged to guide light from the apertures (6) in the masking element (5) to a light dispersing device (8) for dispersing the light from each waveguide (7) into a dispersed spectrum. A light detecting device (10) detects specific spectra in the dispersed spectra of light substantially simultaneously. In one embodiment, the apertures (6) are substantially smaller in size than the emitting area of the reaction vessel, but in another embodiment, the apertures (6) are substantially similar in size to the emitting area of the reaction vessel and the light waveguides (7) have a diameter that tapers from a first end substantially similar in diameter to the area of the top of the reaction vessel to a second end that is substantially smaller in diameter. In an alternative embodiment, the light waveguides are not used, when light from the small apertures is directed straight at the light dispersing device. In a further alternative embodiment, several light waveguides are provided for each reaction vessel, each waveguide directing light to a different detector for detecting a different specific spectrum.
