    Abstract: An apparatus that conducts in situ analyses of fluids in real time is disclosed. The apparatus comprises bifurcated optic fibers, a pulsed light source, a light detector, a water-tight pressure case that houses the pulsed light source and the light detector, and a flow-through cell that receives one end of each bifurcated optic fiber. The flow-through cell may comprise a plurality of attached tube sections that define a volume which acts as a passageway for conducting fluids. One or more sections of the flow-through cell may be adapted to introduce a reagent into fluid flowing through the cell. Sections of the cell may contain potassium periodate and N,N-diethylaniline that are released into a fluid flowing through the passageway, enabling the spectrophotometer to analyze manganese (II) concentrations by monitoring the decrease in fluorescence accompanying the oxidation of DEA to 2 DEA'. The fluid may also be analyzed by measuring reflectance, absorption, turbidity, and fluorescence.

    Abstract: An arrangement through which the concentration of fluorescent materials, when present in low quantities, may be measured within a fluid. A transmitter is flashed periodically at a rate corresponding to the rate that measurements are taken, for the purpose of exciting the fluorescent materials. Filters and optical systems are provided at the transmitter for transmitting the appropriate light. A receiver spaced from the transmitter or light source is also equipped with appropriate filters and optical systems, and receives on a photosensor, the radiation from the fluorescent materials. The resultant electrical signals from the photosensors are amplified and compensated against daylight and cloudy effects of the medium, through an auxiliary amplifier.
