- Description
- The U.S. Department of Commerce (USDOC), Atmospheric Turbulence and Diffusion Division (ATDD) in oak Ridge, TN intends to purchase a G2103 Trace Ammonia for Ambient Air Analyzer from Picarro, Inc. The Atmospheric Turbulence and Diffusion Division of NOAA's Air Resources Laboratory conducts a focused variety of intensive field campaigns related to air quality. In the atmosphere, ammonia (NH3) is the most abundant alkaline trace gas, and contributes to the degradation of regional air quality and affects environmental health. The ammonia cycle is complex, as it is emitted from a variety of natural and anthropogenic sources, reacts readily with other atmospheric gases forming fine particulates, then returns to the biosphere through the atmospheric deposition process. In an effort to better understand the complexities of the ammonia cycle, ATDD requires a variety of resources and technologies specific to ammonia detection and measurement. The Picarro G2103 Cavity Ringdown Spectroscopy (CRDS) system meets these criteria. As the instrument will be deployed on long and short term field campaigns for periods lasting several months, it must be transportable, robust, handling temperature extremes, humidity, and vibrations. The G2103 is transportable and meets criteria for footprint size of approximately 17"w x 7"h x 17.5"d. The G2103 is subjected to a mil-spec drop test and environmental chamber test for humidity and temperature, to verify its operating temperature and humidity specs of 10-35C and 0-99%, respectively. Furthermore, the instrument must be stable over a long term, with certified drift in the ammonia measurement, allowing for science-grade, accurate, quality-assured data. The CRDS technology that the G2103 is built upon meets that criteria with certified calibrations and drift specs. The instrument must respond quickly and precisely, as ammonia can commonly be in concentrations as low as 1.0 ppb. The G2103 guarantees its precision to less than 0.07 ppb within 5 minutes. These are currently the best specifications for a commercially available CRDS instrument. Finally, the instrument must report real time data. Annular denuder systems may take days to render results; however, the G2103 reports real time ammonia concentrations, providing tremendous data quality and resolution. ATDD's requirements for a high quality, real-time gas analyzer designed for ammonia measurements in short and long term field campaigns, such as a Picarro G2103 CRDS system or equivalent, include: 1. The analyzer must operate using the technique commonly known as WS-CRDS (Wavelength Scanned Cavity Ringdown Spectroscopy). 2. The analyzer must be commercially available, single-unit system capable of measuring ammonia concentration, with the following guaranteed precision (1σ) over 5 seconds: NH3 < 1.0 ppb and precision (1σ) over 5 minutes: NH3 <0.07 ppb. 3. The analyzer is required to have a guaranteed response time of less than 30 seconds for a 90% to 10% fall from 3 ppm to 0 ppm and 30 seconds for a 10% to 90% rise from 0 ppm to 3 ppm. 4. The analyzer software must report concentration information in real time, allowing exceptionally quick operator feedback. 5. The analyzer is required to include a customer changeable external filter, for ease of routine instrument maintenance. 6. The analyzer is required to have a sample volume less than 35 ml allowing for extremely fast gas sample throughput and minimal memory. 7. The analyzer is required to have capability for 4 separate laser sources, ensuring future adaptability for additional applications. 8. The analyzer is required to have guaranteed, tested, certified and quoted drift specifications for NH3. 9. The analyzer must be temperature stabilized to within +/- 0.005 °C 10. The analyzer must be pressure stabilized to within +/- 0.0002 atmospheres 11. The analyzer is required to have a wavelength monitor which controls the wavelength of the laser to within 2MHz which allow extremely precise quantification of all required spectral features. 12. The analyzer is required to be subjected to, and must pass, a mil-spec drop test, a vibration test on both axes, and an environmental chamber test. The Picarro G2103 operates using Wavelength Scanned Cavity Ringdown Spectroscopy (WC-CRDS), which provides guaranteed precision (1 sigma) over 5 seconds of NH3 < 1.0 ppb and precision (1 sigma) over 5 minutes of NH3 <0.07 ppb. Also, the Picarro G2103 has a guaranteed response time of less than 30 seconds for a 90% to 10% fall from 3 ppm to 0 ppm and 30 seconds for a 10% to 90% rise from 0 ppm to 3 ppm. The recommendation for purchase of the new Picarro G2103 is based on the operating capability and specific measurement requirements. The G2103 meets or exceeds the twelve requirements listed in the above text. The government only knows of Picarrro G2103 that is capable of meeting requirements for precision, response time, and robustness (capable of operating under extremes in temperature, humidity, and vibrations as experienced in field campaigns). The proposed contract action is for supplies for which the government intends to solicit and negotiate with only one source Picarro, Inc. Interested persons may identify their interest and capability to respond to the requirements or submit proposals. However, all proposals received after date of this publication of this synopsis will be considered by the Government. A determination by the Government not to compete with this proposed contract based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Submissions received in response to this notice shall be evaluated based on the technical ability and demonstrated past experience to meet the requirement. All those interested should submit, in writing, the company name, address, point of contact, telephone number, and business size; a detailed statement regarding technical capabilities and qualifications, and any additional supporting literature. Vendor must provide a DUNS number (http://www.dnb.com/us/) and register with the Central Contractors Registration (Http://www.ccr.gov/) to further qualify for this contract.
