66 -- DESORPTION/CONCENTRATION SYSTEM FOR GAS CHROMATOGRAPH SOL RFQ No. FA6746 POC Deanna Easley, Contract Specialist, 513-366-2027 WEB: Office of Acquisition Management -- Cincinnati Contracts Mgmt. Division, http://www.epa.gov/oam/cinn_cmd. The US EPA, Air Pollution & Prevention Control Division (APPCD), Research Triangle Park, N.C., develops methods to characterize sources of indoor air pollution. This effort requires that APPCD have the capacity to identify and quantify organic vapor contaminants (VOCs) that are emitted to the air by many types of sources. In order to meet the minimum requirements, the unit shall meet the following performance specifications: for a fully integrated and automated thermal desorber and preconcentrator unit capable of (1) automatically thermally desorbing and preconcentrating organic air contaminants collected on 8" long by 0.25" OD sorbent traps; (2) preconcentrating contaminants collected in whole air samples (canisters); and (3) direct concentration of analytes from chambers or sample manifolds. The system shall have a demonstrated ability to manage excessive water and C02 associated with the sample and all transfer tubing shall be temperature controllable and lined with deactivated fused silica to ensure transfer of polar analytes through the system. The system shall be listed and labeled by a third party listing agency approved by the North Carolina Building Code Council. The Government intends to negotiate on a sole source basis for the desorption/concentration system. Requests for a copy of RFQ FA-6746 must be in writing; requests may be faxed to D.
