66 -- INDUCTIVELY COUPLED PLASMA-MASS SPECTROMETER SOL RFP 2078 DUE 082595 POC Contact point Phyllis Yates, Contracting Officer, 415/329-4163, FAX 415/329-5480 The USGS, Water Resources Division, Menlo Park, California, requires an inductively coupled plasma-mass spectrometer (ICP-MS) system. ICP-MS must be fully computer controlled and include all hardware and software required for determination of all ions having mass to charge ratio from 1 to 269 atomic mass units, on microliter as well as normal aliquots, and on a variety of samples generated from field and laboratory investigations including extremely dilute rain and snow samples, brines, acid leaches and solid materials. Capable of analyzing for trace determinations of transition and rare earth elements, actinide and lanthinide groups of elements, and precise isotope ratios for tracer, geochemical and biogeochemical investigations. The ICP-MS system must include the following items: (1) Sample introduction system for water and slurries; (2) Radio frequency plasma ion source; (3) Ion extraction and interface system; (4) Quadrupole mass filter; (5) ETP dual stage discrete dynode detector; (6) Computer controlled and compatible electrochemical vaporization system with autosampler for multielement analysis of 5 or more microliters of water and solids; (7) Computer controlled and compatible flow injection atomic spectroscopy (FIAS) system for flow injection microsampling, vapor generation, dilution and preconcentration. System shall also include IBM compatible, Pentium 90 MHZ computer operable under multitasking operating system such as Windows NT, with the following features: 24 Mb RAM, 1.0 Gb hard drive, double speed CD-ROM drive, tape back up system, 16-bit sound card, 3.5 1.4 MB floppy disk drive, 1 parallel interface and 2 RS-232C interfaces, high resolution 21 SVGA color graphics monitor, and HP Laser Jet 4 or equal printer. System software shall be capable of: automated optimization and instrument tuning; full report generation allowing total user formatting and creation of format templates; comprehensive graphics allowing real time review of data, display of transient and continuous signal profiles and spectral profiles in real time, and overlaid, added, subtracted and ratioed; quantitative analysis including external calibration, method of additions, isotope ratios and isotope dilutions; retaining all raw data on HD. More detailed specifications will be provided in the RFP, which interested parties should request in writing within 15 days of publication of this announcement. Award subject to availability of funds. All responsible sources may submit a proposal which will be considered. (0184)
