Sites (3803-R), U.S. Environmental Protection Agency, Ronald Reagan Building, 1300 Pennsylvania Avenue, NW., (Bid and Proposal Room No. 61107), Washington, D. C. 20004] [STATEMENT OF WORK] The U.S. Environmental Protection Agency (EPA) has a requirement for a wavelength dispersive X-ray fluorescence spectrometer system capable of performing unattended, automated multi-element analysis with high resolution, sensitivity, precision and accuracy. The system shall be composed of a spectrometer, robotic sample changer, computer, and meet the following minimum specifications. 1. The spectrometer shall have inverted optics to permit measurements from the bottom of the sample. 2. The generator and X-ray tube shall be capable of operating continuously at 4 kW (kilowatts). The generator and X-ray tube shall be able to operate at 60 kV (kilovolts) and at a current high enough to reach 4 kW. 3. The X-ray tube shall be a ceramic end window tube with a window thickness of 75 micrometers or less. The tube shall contain a rhodium anode. 4. The spectrometer shall be equipped with at least three primary beam collimators under computer control. The spectrometer shall also have computer controlled collimator masks, which are properly sized to match the sample cups. This includes masks appropriate for analyzing samples 40 mm in diameter and 31 mm in diameter. 5. The spectrometer shall be equipped with a primary beam filter changer, with the proper filters mounted to provide optimal conditions for the determination of all elements from carbon to uranium. The filters shall be optimized for use with the end window rhodium tube supplied with the spectrometer. 6. The goniometer shall have the theta and two theta motions decoupled. Direct optical positioning of the goniometer is required. 7.The spectrometer shall include a crystal changer for the analyzing crystals with at least 8 positions. The following analyzing crystals shall be supplied with the spectrometer: LiF 200, LiF 220, PET, Ge 111, and a multi-layer crystal suitable for oxygen to magnesium. Any other crystals required for the operation of the semi-quantitative, standardless analysis program shall also be included. 8. The EPA requires a spectrometer with three X-ray detectors, a scintillation counter, a flow proportional counters, and a xenon sealed gas detector. All the detectors shall be mounted inside the vacuum chamber. The temperature stability in the vacuum chamber shall be 0.1 degrees Celsius or better. 9. The detection system shall contain a multi-channel analyzer. The counting electronics and circuitry shall be linear to a count rate of one million counts or higher. 10. The spectrometer shall be equipped with a helium flush system so that liquid samples can be analyzed. The spectrometer shall also operate under vacuum (with supplied vacuum pump(s)). 11. A sample changer which can handle at least 24 samples is required. The sample changer shall allow expansion to a capacity of at least 100 samples, without purchase of a complete new changer. The sample changer shall be x and y programmable, and shall allow for a random mix of sample types. In combination with the software it shall be possible to automatically check standards and recalibrate if necessary. 12. The contractor shall supply ten sample holders, five for samples with a 31 mm diameter and five for samples of 40 mm diameter. 13. The contractor shall supply a complete system for cooling the X-ray tube and the spectrometer. The system shall include an air cooled water chiller. 14. The software shall run on Windows 98 or NT. 15. The instrument software shall allow data to be easily and seamlessly transferred to an Excel spreadsheet. 16. The spectrometer software shall permit easy archival of data and analytical programs. At least three operators shall be able to maintainseparate files with all their calibration, results and other data. These operators shall be able to archive their old projects, backup current projects, and retrieve archived work to restore the system after crashes or malfunctions. Any new software which the spectrometer manufacture offers within 12 months of delivery shall be free, and include permission to load the software on three separate EPA computers at no charge. 17. The spectrometer shall be warranty for one year, and shall include parts, labor, and travel expenses. The tube shall be fully warranted without proration for a period of two years, and includes labor and travel expenses. The warranty shall apply to all replacement tubes as well. 18. The spectrometer shall be easily serviced in case of problems. The manufacture shall have service engineers located in the United States readily available who are fully trained on the instrument, and who can travel in a timely manner to the EPA National Enforcement Investigations Center laboratory at the Denver Federal Center, Denver, Colorado. 19. The spectrometer shall have remote diagnostic capabilities, with the service engineers being able to access the spectrometer through a modem and a telephone line. The remotely located service engineers shall be able to operate the instrument and diagnose problems. These remote diagnostic capabilities shall be independent of the instrument computer. The instrument itself shall be able to be connected directly to a phone line. Data and programs on the computer shall not be accessible to a remote serviceman. 20. The spectrometer shall be mounted on sturdy wheels, and shall meet all of its operating specifications while mounted on its wheels.. 21. The manufacture shall provide documentation that the spectrometer system meets the specifications. The documentation shall include testing results for the actual instrument delivered to the EPA 22. The contractor shall supply a computer capable of operating the instrument and running all of the software. At a minimum, the computer shall include components equal to or better than the following: An Intel 450 MHZ Pentium processor, a 15 Gb hard drive, a 32x CD ROM drive, a 3.5" diskette drive, and a 21" color monitor. A Hewlett Packard Deskjet 970Cse printer able to print graphic and alphanumeric results shall be included. 23. The software shall provide all necessary options for qualitative and quantitative analyses. Qualitative scans shall be labeled with the most probable elements and lines. Quantitative measurement software shall support all of the common matrix correction algorithms, including fundamental parameters. Quantitative results shall be exportable into an Excel spreadsheet. All software upgrades which the manufacture offers shall be made available for free to EPA for one year after delivery. 24. A state of the art fundamental parameters or "standardless" program for semi-quantitative analysis shall be part of the software. Uniquant from Omega Data Systems or equivalent is acceptable. If an equivalent program is offered, the contractor shall provide a detailed description of the program, including detection limits. 25. The Contractor shall install the spectrometer at the EPA National Enforcement Investigations Center laboratory at the Denver Federal Center, Denver, Colorado. 26. The contractor shall supply a complete set of the operating and service manuals for the spectrometer. The manufacture shall provide at least 3 days of on-site training within 15 days after spectrometer installation, as well as tuition for one EPA chemist to attend the basic XRF training course at the manufacture's applications laboratory. **This combined synopsis/solicitation announcement constitutes the only solicitation. No other written solicitation will be issued. Proposals shall be received no later than 4:00PM local time Washington, D.C. on July 17, 2000.** Posted 06/27/00 (W-SN468945). (0179)
