66 -- MASS SPECTROMETER SOL C600567T1 POC Contact Point, Cynthia Johnson, (513)366-2040, Contracting Officer, Lisa Bentley, (513)366-2041 Solicitation C600567T1; POC: Cynthia Johnson. The U.S Environmental Protection Agency (EPA) National Exposure Research Laboratory in Cincinnati, Ohio (NERL-CI) has a need for a contractor to provide and install an inductively coupled plasma mass spectrometer (ICP-MS). The ICP-MS will be used primarily to research the speciation of mercury and other metals in complex matrices using isotope tracers, liquid chromatography and direct injection nebulization. Other significant usage will be for non-routine samples such as food, and for performance of EPA Method 200.8 when required by EPA special projects. The ICP-MS unit must consist of an argon plasma ion source, a mass filter, an ion detection system, all equipment necessary for maintenance of high vacuum, and hardware and software necessary for instrumentation control, direct injection nebulization, data acquisition, reduction, presentation and storage. Other necessary key features are high absolute sensitivity, excellent abundance sensitivity, ability to detect transient signals, the ability of the plasma to tolerate 100% organic matrix, low memory effects for mercury, good short and long term stability, and high isotope ratio precision. The ICP-MS must be a full production unit, not a prototype, demonstration, used or preproduction run model. All responsible sources may submit a proposal which, if timely, will be evaluated by the Agency. All requests for a copy of the solicitation must be in writing. No telephone requests will be honored.
