  • Fiber-optic pipette (FOP) for rapid long pathlength capillary spectroscopy
    Patent number: 6091490
    Abstract: The fiber-optic pipette (FOP) couples a glass capillary, common syringe and a single optical fiber together to provide for a facile means of achieving long-pathlength capillary spectroscopy. The FOP acquires rapid spectroscopic measurements of small-volume liquid samples, while simultaneously achieving signal enhancements of the collected spectroscopic signal.

  • Apparatus and method for monitoring steel decarburization by remote flame emission spatial imaging spectroscopy
    Patent number: H1925
    Abstract: An apparatus and method for monitoring a stainless steel decarburization cess includes a flame emission spatial imaging spectrometer and a telescopic lens system coupled to the spectrometer. The telescopic lens system is positioned to direct light from the furnace flame into the spectrometer. The flame emission imaging spectrometer and the telescopic lens system are located at a remote distance away from the harsh environment of the furnace flame.
