  • Patent number: 9581493
    Abstract: A spectrometer is provided for acquiring a Raman spectrum from a sample. The spectrometer includes a first laser, a second laser, a detector and a processing device. The first laser is adapted to produce a first laser beam for generating first Raman spectra from the sample. The second laser is adapted to produce a second laser beam for generating second Raman spectra from the sample. The detector is adapted to collect the first Raman spectra and the second Raman spectra. The processing device is adapted to process the collected first and second Raman spectra to provide the Raman spectrum.

  • Patent number: 6061134
    Abstract: A modification to a commercial Fourier Transform (FT) Raman spectrometer is presented for the elimination of thermal backgrounds in the FT Raman spectra. The modification involves the use of a mechanical optical chopper to modulate the continuous wave laser, remote collection of the signal via fiber optics, and connection of a dual-phase digital-signal-processor (DSP) lock-in amplifier between the detector and the spectrometer's collection electronics to demodulate and filter the optical signals. The resulting Modulated Fourier Transform Raman Fiber-Optic Spectrometer is capable of completely eliminating thermal backgrounds at temperatures exceeding 300.degree. C.

  • Patent number: 5892228
    Abstract: A Fourier-Transform Raman spectrometer was used to collect the Raman spectra of (208) commercial petroleum fuels. The individual motor and research octane numbers (MON and RON, respectively) were determined experimentally using the industry standard ASTM knock engine method. Partial Least Squares (PLS) regression analysis can be used to build regression models which correlate the Raman spectra (175) of the fuels with the experimentally determined values for MON, RON, and pump octane number (the average of MON and RON) of the fuels. Each of the models was validated using leave-one-out validation. The standard errors of validation (SEV) are 0.415, 0.535, and 0.410 octane numbers for MON, RON, and pump octane number, respectively. By comparing the standard error of validation to the standard deviation for the experimentally determined octane numbers, it is evident that the accuracy of the Raman determined values is limited by the accuracy of the training set used in creating the models.

  • Patent number: 5596196
    Abstract: Oxygenated hydrocarbons can be predicted within .+-.0.2% wt or better, using Raman NIR spectroscopy and multivariate analysis, with optional fiberoptics multistreaming. The resulting signal can be used to control concentration of such compounds in product to desired levels.
