66 -- PORTABLE X-RAY SPECTROMETER SOL W501416-A2 DUE 090195 POC Contact Point, Jennifer Johnson, (202)260-0671, Contracting Officer, Rodney P. Magee, (202)260-6455 The National Enforcement Investigations Center (NEIC) of the U.S. EPA requires the services of a contractor to provide a portable X-Ray Fluorescence Spectrometer which can be handcarried and operated by one person. The probe containing the sources and the dector should have a laboratory stand and also be capable of placement against the ground. The electronic unit must be able to convert measured intensities into elemental concentrations, and be able to store at least 25 spectra and 25 sets of sample results. In addition to 110 volt AC operation, it must operate on self contained batteries for at least two (2) hours. The detector must be capable of operation at ambient temperatures, and must not require cooling with liquid nitrogen. The resolution of the detector must be 300 eV or better when measured at the manganese K-alpha line. The instrument software must include fundamental parameters calibration procedures as well as provisions for empirical calibration. Results and spectra must be transferable to a PC. A Firm Fixed Price contract is contemplated with an effective date of 10/1/95. All interested offerors shall submit a written request for RFP No. W501416-A2 to Jennifer T. Johnson, Contract Specialist, U.S. EPA, Administrative Placement Section (3803-F), 401 M Street, S.W., Washington, D.C. 20460. (0227)
