Description

Pacific Northwest National Laboratory (PNNL), operated by Battelle Memorial Institute under contract to the U.S. Department of Energy, solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology (hereinafter referred to as "technology"). License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. PNNL may also be available to licensee(s) to assist in further research and development of the technology under a sponsored research agreement or CRADA program. This technology describes an accurate measurement of dithionite concentration. When deploying in-situ redox manipulation techniques for groundwater remediation, accurate measurement of the dithionite concentration is needed in laboratory and field experiments in order to assess the reduction of the sediment and ultimately the effectiveness of the in situ redox manipulation technique. Once dithionite is put in aqueous solution, it will degrade to a number of different sulfur-containing compounds over several hours, so accurate measurement of only the dithionite concentration needs to be accomplished as soon as possible. While dithionite can be accurately measured in the laboratory with several techniques (direct titration, liquid chromatography, or gas chromatography-mass spectrometry), these rely on fairly expensive ($40K to $70K) equipment and additional laboratory resources including an anaerobic chamber to provide an oxygen-free environment during sample processing. These techniques require considerable resources are not practical for remote field locations. The technique described in this invention report was developed over several years of laboratory and field experiments based on the necessity for fast and accurate measurement of dithionite concentration at remote field locations. Patent Pending. Novel aspects of this invention include: A novel fluid analysis system for perfoming automated fluid analysis over a widely varying concentration range. A novel fluid analysis system for perfoming automated groundwater analysis during a remediation injection, especially for injection of dithionite. Able to monitor levels of soil chemicals following a remediation injection. Note: THIS IS NOT A PROCUREMENT. Any company interested in licensing this technology must respond with a letter of interest (may be submitted by e-mail) no later than 30 days from the publication date of this Notice summarizing the company's business and technical expertise and motivation for pursuing this opportunity. Companies deemed appropriate will be provided with further information on the technology. Such information may require an executed Nondisclosure Agreement. Respondents wishing to enter into negotiations for a commercial license will be required to submit a business plan for the commercialization of the technology prior to licensee selection and negotiations. Please send letters of interest to the attention of the POC identified within this Notice.
