  • Patent number: 6747735
    Abstract: A multiplex coherent Raman spectrometer (10) and spectroscopy method rapidly detects and identifies individual components of a chemical mixture separated by a separation technique, such as gas chromatography. The spectrometer (10) and method accurately identify a variety of compounds because they produce the entire gas phase vibrational Raman spectrum of the unknown gas. This is accomplished by tilting a Raman cell (20) to produce a high-intensity, backward-stimulated, coherent Raman beam of 683 nm, which drives a degenerate optical parametric oscillator (28) to produce a broadband beam of 1100-1700 nm covering a range of more than 3000 wavenumber. This broadband beam is combined with a narrowband beam of 532 nm having a bandwidth of 0.003 wavenumbers and focused into a heated windowless cell (38) that receives gases separated by a gas chromatograph (40). The Raman radiation scattered from these gases is filtered and sent to a monochromator (50) with multichannel detection.

  • Patent number: 5736048
    Abstract: In a process of remediating chemical contamination of a pond contaminated with one or more toxic heavy metals or aromatic compounds, the steps include: preparing a silage of grass clippings, placing the silage on the surface of a pond, and inoculating the pond with an alga and Bacillus cereus in sufficient quantities to cause a mixed algal and bacterial bloom to form on the pond surface and become annealed to the silage, leaving the silage with the annealed bloom on the surface of the pond for a sufficient amount of time to allow the bloom to withdraw at least some of the toxic heavy metal content or to degrade at least some of the aromatic compound content of the pond, and removing the silage with the annealed bloom from the pond.
