DEVELOPMENTS AT NIST Researchers at the National Institute of Standards and Technology (NIST) have developed a new technology. Anyone interested in the further development of this technology or in applying for a license to commercialize this technology should send a written request for further information, referencing the NIST Docket Number and Title, to: Marsha Salkeld, National Institute of Standards and Technology, Industrial Partnerships Program, Building 820, Room 213, Gaithersburg, Maryland 20899; Telecopy: 301-869-2751. This is not an announcement of a contract action or a grant. NIST Docket Number: 95-046PA, Title: Portable Benchtop Fourier Transform Microwave Spectrophometer for Trace Gas Analysis, Description: The invention describes a Fourier transform microwave spectrometer. The device is an improvement over existing microwave spectrometers in that it has improved the typical signal-to-noise ratio by using a cryogenically-cooled amplifier; has fast real-time sampling by using a pulsed molecular beam for sample introduction; and has better resolution by the use of dual microwave antennas to better resolve molecular signals. A detection limit of 3 ppb has been demonstrated. An application has been filed with the US Patent and Trademark Office. The primary market for this invention is trace gas analytical instruments. Secondary markets that would use this technology include industrial emission measurement, hazardous waste management, analytical chemistry equipment, and other low-detection limit applications such as automotive emission research and hazardous cargo detection equipment.
