  • Patent number: 7280204
    Abstract: A multi-spectral detection and analysis system detects and classifies a targeted sample. The system may include a light source that causes the targeted sample to luminesce. A light dispersion element disperses the luminescence to a photodetector in a photodetector array. Each photodetector in the array transmits a signal indicating a portion of the spectrum to a multi-channel collection system. The multi-channel collection system processes the signal into a digital signal and forms the digital signal into a spectral signature. A processor analyzes the spectral signature and compares the spectral signature to known spectral signatures to identify the targeted sample.

  • Publication number: 20060017008
    Abstract: A method for photochemical reactor characterization includes an application of using dyed microspheres exposed to UV irradiation under a collimated-beam system. Particle specific fluorescence intensity measurements are conducted using samples form the collimated beam and flow-through reactor results using flow cytometry. A numerical model may be used to simulate the behavior of the reactor system to provide a particle-tracking algorithm to interrogate the flow and intensity field simulations for purposes of developing a particle specific estimate of the dose delivery. A method for measuring UV dose distribution delivery in photochemical reactors is provided that includes introducing microspheres labeled with a photochemically-active compound in a UV reactor, The labeled microspheres are harvested downstream of the irradiated zone of a UV reactor and exposed to UV irradiation under a collimated beam of UV irradiation.
