  • Systems and Methods for Monitoring Phenanthrene Equivalent Concentrations
    Publication number: 20150041682
    Abstract: The present application is directed to systems methods and methods for monitoring phenanthrene equivalent concentrations in an aqueous stream. One or more sources of electromagnetic radiation at different wavelengths may be directed into a sample of the aqueous stream and the resulting fluorescence at various wavelengths is detected. The detected fluorescence is then used to determine the phenanthrene equivalent concentration.

  • Submersible apparatus for measuring active fluorescence
    Patent number: 7470917
    Abstract: A submersible fluorometer for measuring a fluorescence of a photosynthetic material in a liquid, the fluorometer includes a set of light emitting diodes (LEDs) for supplying light to direct towards the liquid and a photodiode for measuring a detected light emitted from the liquid. The light is used for measuring the fluorescence of the photosynthetic material in the liquid. The fluorometer also has a water-tight volume for protecting the photodiode from the liquid.

  • In-line spectrometer
    Patent number: 7099012
    Abstract: Some embodiments of the invention provide an improved spectrometer that measures light emissions and/or reflection from a non-solid material that flows through a system of pipes. This spectrometer is designed to fit into a standard pipe system. The material flows past a distal end of the spectrometer that is inserted in the pipe system. The spectrometer has the ability to project light onto the material and collect a resulting light from the material through the distal end as the material flows past this end.
