66 -- X RAY FLUORESCENCE INSTRUMENT SOL Quote #084-98 DUE 092998 POC Alvin Wong, (415) 744-1023 E-MAIL: Contracting Officer, Wong.alvin@epamail.epa.gov. Specifications for XRF instrument One x-ray fluorescence (XRF) instrument that meets the following criteria: 1. The XRF shall be portable and suitable for use on projects for site characterization on Comprehensive Environmental Response Compensation and Liability (CERCLA) projects in the ambient environment without the need for accessories or supplies that would preclude use at sites remote from access to running water, gas supplies, and electrical power. In particular the XRF must: 1A. The XRF shall be a complete system. The XRF shall include all necessary supplies, accessories, and consumables such that upon receipt the system shall be capable of operation to perform analysis of soil, filter, or lead in paint on building surfaces analyses. Sufficient quantity of consumable supplies to perform 500 soil analyses for quantitative analysis of lead shall be included. A soil grinder with removable assembly for soil homogenization that holds the sample during grinding shall be included. (Accessory items such as soil grinders and battery recharger can utilize 110 -- 120 V 50/60 Hz electrical power source). 1B. The XRF including sample holder, optics systems, readout and display system, and data storage system must be light weight. The ideal complete system will less than 10 pounds. 1C. The complete XRF system must not require external cooling supplies such as liquid nitrogen. 1D. The XRF must be capable of performing display of data and calibration using site-specific calibrators made from site soil for metals in soil analyses. In addition, the necessary software and accessories for storage of data, processing of data including deconvolution of overlapping spectral peaks, use of common calibration algorithms, measurement of multiple metals, and transfer and reporting of data to an IBM-compatible computer via a common standard interface such through cable to the computer's serial or parallel port. 1E. The XRF must have necessary systems in place to provide stability in environments where ambient temperatures or other weather conditions may change during use. For example, the XRF must have temperature control of the detector and must be of sufficient rugged design that outdoor use is practical. The XRF must be usable in ambient temperature that may be from 32 to 100 degrees Fahrenheit, and ambient humidity from 0 to 90% RH. 1F. The XRF must include a waterproof and rugged carrying casesufficient with a locking device to allow shipment, under normal and usual conditions, of the XRF via Federal Express, or storage in a car trunk during transportation with damage to the instrument. Must conform to 49 CFR 173.421. Include a light-weight carrying bag for on-site use. 1G. The XRF must have sufficient rechargeable battery packs to allow 24 hours of use, along with an adapter to allow recharging of the batteries using a 12 V DC car lighter. 1H. The XRF system must include 3 sets of manuals for operation and maintenance of the system and accessories. 2. In order to allow the use of the XRF for as wide a range ofanalytes as possible the instrument must contain three sources that may be interchanged without exposing the operator to direct contact with the sources. The three sources must be Cadmium-109, Iron-55, and Americium-241. In addition, the XRF must be capable of measurement of as wide a range of analytes as practical which is the elements sulfur through plutonium on the periodic table. Cd-109 source must be at least 10 milli-curries. 3. Due to generation of data under regulatory programs including HUD regulations and need for public and technical acceptance of XRF generated data for lead, the XRF must be able to show proficiency in the American Industrial Hygiene Association (AIHA) Environmental Lead Proficiency Analytical Testing (ELPAT) Program which is mandatory for laboratories seeking accreditation under EPA's National Lead Laboratory Accreditation Program (NLLAP). The XRF vendor is responsible for providing adequate documentation of ELPAT proficiency for lead in soil, paint chips, and dust wipes in a timely manner. Delivery of the instrument will not be contingent on the delivery of the ELPAT proficiency data for lead. 4. The complete XRF system must be delivered NLT than January 1999 to EPA Region 9 unless EPA Region 9 requests a later delivery date, however, the later delivery date must be before March 1999. Due to licensing issues, the delivery date will be negotiated with EPA for a date that is mutually acceptable within criteria delivery time criteria already specified. 5. The system shall include necessary training for up to ten individuals to operate and maintain the instrument, as well to provide an understanding of relevant state and federal regulations concerning transportation, storage, and use of an XRF with the required radioactive sources. 6. The XRF shall be capable of 3-sigma detection limits using a 60 second measurement of not greater than stated below for the corresponding metals: Barium 200 ppm Arsenic 75 ppm Selenium 75 ppm Silver 100 ppm Lead 30 ppm 7. To take into account rapid changes in the technolgy, the package shall include all offered upgrades in processing and reporting software for 18 months, and detector upgrades for 6 months, after receipt of the XRF system. 8. The system shall have a minimum 3 year extended warranty and maintenance contract covering defects, accessories and system parts (including sources) that are expected to wear out, and periodic maintenance that is recommended by the vendor to be performed by the vendor. This shall included a one-time replacement of the Cd and Iron sources at a time requested by EPA (EPA will give a 45 day notice to the vendor of any source change requests). This contract will provide the necessary service including shipping between EPA and the vendor at no financial cost to EPA unless the damage or defect was caused by intention, Act of God, or otherwise from practices recommended against by the instruments users manual. 9. The system shall include necessary software for statisical processing of data and presentation such as Sigma Plot, or equivalent. The platform to archive and process data using the statistical software should be included and be considered part of the XRF system; the platform shall be battery powered and include an extra battery.
