- Description
- NAICS Code: 334516 The U.S. Environmental Protection Agency's (EPA) Office of Air and Radiation (OAR) Office of Atmospheric Programs (OAP) Clean Air Markets Division (CAMD) intends to award a sole source Purchase Order to Tekran Instuments Corporation under the authority of Federal Acquisition Regulation (FAR) part 13, Simplified Acquisition Procedures for two Ambient Mercury Trace Level Monitoring Systems and a Mercury Calibration Unit. Tekran Instruments Corporation is the only known source able to provide the required systems with the following attributes to the Government: Ambient Mercury Trace Level Monitoring Systems: 1. The analyzer shall be a self-contained, rack mountable unit, with internal pump, user-serviceable pre-concentration traps, heaters, mass-flow meter & controllers, a cold vapor atomic fluorescence detector, and calibration source. 2. 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. 3. 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. 4. The analyzer must be equipped with dual, gold-column amalgamation cartridges which 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. 5. 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. 6. 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. 7. 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. 8. 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. 9. 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. 10. The analyzer must utilize an electronic mass-flow meter or controller to measure ambient air sample flow rate. If using a mass 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. 11. 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. 12. 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. Mercury Calibration Unit: 1. Compatible with existing EPA/CAMD mercury sampling equipment, manufactured by the Tekran Corporation. 2. Utilize a syringe to manually inject a precisely known amount of elemental mercury into the analyzer to be calibrated. 3. Interface directly with digital syringes allowing continuous measurement of volume and instantaneous calculation of injection amount. 4. Rugged and self-contained, and portable to make it suitable for laboratory or field use. 5. Small (less than 16 x 12 x 12 inches) and weigh less than 12 pounds for portability. 6. Draw less than 2.5 amps max (12 VDC) when operating on battery power. 7. Precisely regulate the temperature of the elemental mercury reservoir with a thermoelectric cooler, not a water bath, and precisely measure chamber temperatures and display them with digital display. 8. Operate with line power or battery backup (12 VDC). 9. On-board microprocessor to automatically calculate amount of mercury injected based on either measurements or input temperature and volume. 10. Serial port to allow logging of injections, temperatures and other instrument parameters. 11. Contain a pool of liquid mercury within a Teflon? vessel, entirely enclosed within an insulated isothermal block. A Teflon? backed silicone septum must be used to seal the vessel. 12. Contain two precision sensors, one to measure the temperature of the isothermal block and one to monitor the temperature within the vapor chamber. 13. Temperature control accuracy of ?0.05?C with resolution of .001?C 14. Measured temperature range of -5 to +50?C 15. Selectable temperature range of 0- 30?C (Setpoint must be below ambient temperature) with an accuracy of ?0.05?C and a stability of ?0.01?C Microprocessor and Communications Interface within the Mercury Calibration Unit: 1. Internal microprocessor with LCD and direct access keypad. 2. Measure and display temperature of mercury chamber. 3. Control and display the temperature of the cold block containing the Teflon chamber. 4. Allow input of injection volume (either manually or automatically) to facilitate calculation of injected amount of elemental mercury. 5. Calculate amount of elemental mercury injected into detector. 6. Control internal battery charging and power management systems. 7. Log temperatures, injections and internal parameters to RS-232 serial port NO SOLICITATION OR REQUEST FOR QUOTE WILL BE MADE FOR THIS PROCUREMENT. No contract will be awarded on the basis of offers received in response to this notice. All comments and questions regarding this procurement shall be addressed in writing to the Contracting Officer, Andrea L. Brunsman by COB on September 24, 2007. Telephone inquiries will not be accepted. The decision not to compete this requirement is within the discretion of the Government. Any response to this notice shall show clear and convincing evidence that competition would be advantageous to the Government in future procurements.
