Description

NOAA/ARL requires a Mercury Vapor Analyzer that meets the following requirements: 1. The analyzer shall be a compact, self-contained, rack mountable unit, complete with internal pump, user-serviceable pre-concentration traps, heaters, mass-flow meter & controllers, a cold vapor atomic fluorescence detector, and calibration source. It must be a portable unit that may be used indoors or in the field to monitor background vapor-phase mercury levels to a detection level in the *sub-ng/m3* regime at a cycle time of 5 minutes or less. 2. The analyzer must be capable of operation without an external data-logger or computer, and should possess analog, digital and RS-232 outputs to allow it to be integrated with a serial data-logger, PC-based data system or any air quality telemetry system. 3. The analyzer must be equipped with dual, gold-column amalgamation cartridges with allow for true, _continuous_ sampling of an air stream, with no gaps in the data collected. While one cartridge is sampling ambient air the other is in the process of being analyzed. 4. The mercury vapor cartridges should be made of pure gold, and should be able to withstand many thousands of sampling and desorption cycles without degradation in performance. 5. The duty cycle must be sufficiently short as to allow for near-real-time data collection, with a minimum rate of not more than 2.5 minutes per cycle. 6. The analyzer must be equipped with an internal mercury calibration source that allows the instrument to re-calibrate itself automatically; thus allowing unattended operation for extended periods of time. 7. The analyzer must be equipped with a bypass valve that prevents contaminated air from coming in contact with the detector, thus making cleaning operations infrequent. 8. The detector in the analyzer must have an inert gas purge feature to improve stability, thus necessitating only infrequent adjustments to the GAIN and SENSITIVITY controls. 9. The analyzer must utilize an electronic mass-flow meter or controller to measure ambient air sample flow rate. If using a mas flow meter, the analyzer must utilize a microprocessor controlled feedback loop between the mass flow meter and pump to ensure accurate sample flow rates and sample volume measurements. 10. The analyzer must use an electronic mass-flow controller to regulate carrier gas flow during analysis, and should automatically shut off gas flow in the event of a power failure. This allows optimal usage of the UHP Argon carrier gas. In addition to the Vapor Analyzer, a Speciation Unit and Particulate Mercury Unit will also be acquired using simplified acquisition procedures in accordance with the Federal Acquisition Regulation (FAR) Part 12 through Federal Acquisition Circular (FAC) 2005-8. These analyzers must be sensitive enough to meet the needs of the ARL in measuring reactive gaseous mercury, elemental mercury vapor or particulate mercury in the atmosphere. These analyzers must be rugged/stable enough to be deployed in the field and left unattended for long periods of time. Any offeror who believes they can comply with the above requirements must submit a written narrative demonstrating the ability to meet these requirements within 10 days of this notice to Robin.Prather@noaa.gov. A determination by the Government not to open the requirement for competition based upon responses to this notice is solely within its discretion.
