66 -- X-RAY FLOURESCENT SPECTROMETER SOL HAQ001006 POC Tom Fulton, 503-952-6218 or FAX 503-952-6312 E-MAIL: BLM, or952mb@or.blm.gov. The Bureau of Land Management proposes to noncompetitively issue a purchase order with NITON Corporation, 63356 Nels Anderson Road, Suite 2, Bend, OR 97701 for the purchase of an XL 702S X-Ray Flourescent Spectrometer (XRF). The purpose of purchasing an XRF is to identify and quantify the existence of heavy metals in soils, namely mine tailings. The XRF must include the following salient characteristics: Operation: 1)The XRF must be capable of demonstrating ELPAT proficiency and must meet the instrument specification for EPA Method 6200: Field Portable X-Ray Fluorescence Spectrometry For the Determination of Elemental Concentrations in Soil and Sediment. 2)The XRF must use a cadmium-109 source and be upgradeable for use with americium-241 and iron-55. The cadmium-109 source must be at least 40 millicuries. 3)The system must detect and display quantities of the following elements using the cadmium-109 source: arsenic, chromium, cobalt, copper, iron, lead, manganese, mercury, molybdenum, nickel, rubidium, selenium, strontium, titanium, zinc, zirconium. 4)The system must be capable of detecting and display quantities of the following elements using the americium-241 source: antimony, barium, cadmium, indium, iodine, palladium, silver, tin. 5)The XRF must not require site-specific calibration and must always self-calibrate before testing is enabled. 6)System must include an automated, barcode-based, data-entry system for site and sample information. This data system must be fully integrated and compatible with the downloading and reporting software. 7)The display must show numerical quantities of heavy metals as well as the complete x-ray spectrum from 3 KeV to 88 KeV for each reading. 8)Cooling of the detector must be obtained with peltier cooling and regulated to at least -20 C. Radiation: 1)Radiation exposure on user's hand with safety shutter open, as during a reading, shall not exceed 0.1 mR/hour. 2)For travel and shipping, the XRF must not require radiation label on the carrying case and must conform to 49 CFR 173.421 for "excepted package," instruments and articles, N.O.S. UN2910. Size: This instrument must be single, self-contained unit, weighing no more than 3 lbs, including batteries. Exterior dimensions must not exceed 9" x 3" x 2". Warranty and Service: The XRF must come with a minimum one year warranty on manufacturer's defects. Also, the manufacturer must supply de-shimming, re-sourcing and other maintenance services on a regular basis for all equipment. A determination by the Government not to compete this proposed acquisition based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Responses due no later than January 3, 2000 by 4:15 p.m., local time. Posted 12/14/99 (W-SN408435). (0348)
