66 -- INDUCTIVELY COUPLED PLASMA MASS SPECTROMETER SOL RFQ-OH-97-00092 POC Contract Specialist, J. Deanna Easley (513-366-2027), Contracting Officer, Sandra Savage (513-366-2046) WEB: Office of Acquisition Management -- Cincinnati Contracts Management Division, http://www.epa.gov/oam/cinn_cmd. The US EPA, National Exposure Research Laboratory, Cincinnati, OH, requires an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) for use in metal speciation and disinfection by product research. A brief description of the ICP-MS instrument follows. The ICP-MS instrument shall: (1) use an argon ICP as an ion source for the mass spectrometer; (2) shall have the necessary hardware and software to control the entire instrument including sample introduction, ICP RF power and tuning, ion lens focusing, vacuum capability and safety interlocks, quadrupole mass calibration and scanning and ion detection and data processing; (3) detection limits in the fractional ppt concentration range; (4) abundance sensitivity greater than 1.0 x 10 (to the -6 power) (high side); (5) greater than 1.0 x 10 (to the 8 power) cps/ppm In absolute sensitivity; (6) ability to acquire a transient signal and provide chromatographic peak integration software; (7) the data collection and handling system must allow for isotope ratioing capability on chromatographic (CE,IC,LC) peaks; (8) 2-3% short (20 min)/long term (2 hrs) precision at 10ppb; and (9) less than 0.2% isotope ratio accuracy at 5ppb are required. A firm fixed price contract is contemplated. All requests for a copy of RFQ-OH-97-00092 must be in writing; requests may be faxed to D. Easley at 513-366-2004. No telephone requests will be honored.
