66 -- INSTRUMENTS AND LABORATORY EQUIPMENT POC Charlene Galanty, Contract Specialist, (703) 814-4906. The Federal Bureau of Investigation (FBI) intends to negotiate on a sole basis with Amray who is the U.S. distributor for the Atomika's Extra IIA-Multi Element Trace Analyzer System with cooling system with heat exchange. This will be a one-time purchase and will include a one year warranty which covers installation, standard parts, emergency and routine service (excluding x-ray tubes, which are warranted for 2,000 hours, prorata.) Operator training is provided upon installation. The requirement is for a commercially available, nondevelopmental, multi elemental analyzer utilizing total reflection x-ray fluorescence (TXRF) technology. The instrument provided must be capable of analysis of microgram sized samples of forensic interest. The TXRF instrument will be used for research concerning characterization of fiber, glass fragments, toxicological samples such as hair, blood, and tissues, metal transfers, paint chips, particles of forensic interest, such as gunshot primers and particles generated by detonation of explosive devices, and enviromental samples. The vendor shall supply the FBI Laboratory with a TXRF system with the following analytical capabilities. These capabilities must be demonstrated by the unit delivered following installation in the FBI Laboratory: (1) provide both qualitative spectral scans and full quantitative determinations of the maximum range of elements possible by TXRF, (2) store profiles of elements to be analyzed and calibration factors in the system once with recalibration required no more frequently than semiannually, (3) have detection limits (3 sigma) in the picogram range for representative, interference free elements across the analyzed mass range, (4) provide precision of better than 5% rsd for repeated measurements of interference-free elements present at nanogram levels in a simple (aqueous) matrix. A system providing these capabilities will typically consist of the following components: (1) X-ray generator with an output suitable for driving two 2 kW x-ray tubes (3.5kW). Control and operation with two x-ray tubes must be suitable to provide the stability required for a high precision analytical instrument. Control x-ray generation parameters and safety interlocks must be controllable from a microprocessor console, (2) molybdenum and tungsten micro focus x-ray tubes, each with 2 kW max power with separate tube housings with filter holder and shutter. Components 1 and 2 may be replaced with another configuration involving a single x-ray tube of appropriate wattage and secondary targets or filters to provide the appropriate wavelength control of sourve x-rays (3) total reflection unit suitable for TXRF signal acquisition. X-rays impinging upon the sample surface must meet the energy and geometric requirements of TXRI, i.e., incident at less than 0.50 from the sample surface, (4) Si(Li) detector with 80 mm2 surface area and energy resolution better thatn 168 at 5 keV, (5) analysis system consisting of a multichannel analyzer with detector electronics and a PC (minimum 4 MB RAM, 80486 66 MHZ processor, 520 MB hard disk, 1.2 MB floppy drive, 1.4 MB floppy VGA video adapter plus monitor, and I/O board and RS 232 and centronics), and black and white printer, (6) sample carrier with capability for multiple samples, programmable sequencing, with single and multiple measurement capability on each sample. Holder must be capable of holding solid samples and evaporated solutions, (7) software for operation of the sustem including programs for system control, data acquisition, data reduction, quantitative analysis, preparation of reports and graphical representation of spectra, and (8) manufacturers warranty to include installation, standard parts, emergency and routine service, operating training upon installation, support include free upgrades of all software, and telephonic applications support. Vendors able to meet this requirement are invited to identify their interest and capability by submitting a company brochure and pricing documentation within forty-five (45) days of this publication. If no affirmative responses are received within this time that clearly establishes a comparable source more advantageous to the government,negotiations will take place with Amray on a sole-source basis. All inquiries shall be in writing to the above address and marked to the attention of Charlene Galanty, Contract Specialist. No telephone inquires or requests for documents will be accepted.
