66 -- GAS CHROMATOGRAPH -- MASS SELECTIVE DETECTION ANALYTICAL SYSTEM SOL ORD -- 32 POC BILLY ODEN, Contracting Officer, (513)487-2126 E-MAIL: U.S. EPA -- Cincinnati Contracts Management Division, oden.billy@epamail.epa.gov. The U.S. EPA has a need for a Gas Chromatography-Mass Selective Detection (GC-MS) analytical system to provide the advanced technology that will enable analysis of human tissue samples for environmental toxicants. These toxicants will include pesticides, endocrine disruptors and exposure biomarkers. The GC-MS system shall also provide ultra-trace sensitivity coupled with selectivity which is required when analyzing human and/or environmental samples. Generally, the GC-MS system shall: include a Mass Selective Detector and Ion Gauge Controller; have vacuum pumping systems, electronic impact and negative ion detection systems. The Gas Chromatograph shall have simultaneous multiple detector capability; a capillary stainless steel inlet system with electronic pneumatic control (EPC) to provide digital control of column head pressure, column flow rate, split ratio and all other pneumatic parameters. Detectors must include Flame Ionization and Nitrogen-Phosphorus all with EPC and an automated liquid sampler with GC-MS interface. All components shall be interfaced and controlled from a data system. The system shall have a searchable GC-MS spectral library for identification of trace compounds. Detailed specifications will be released with the Request for Quotation (RFQ). The RFQ will be released on 12/17/98 with the due date for quotations, 01/05/99. This acquisition will be performed according to Simplified Acquisition Procedures (FAR Part 13). Requests to receive a copy of the RFQ can be mailed to Contract Management Division at the above address; e-mailed to the address below; or sent via facsimile to (513) 487-2109. All requests should include a complete mailing address and a facsimile telephone number. Posted 12/01/98 (W-SN275965). (0335)
