66 -- AUTOSAMPLER INSTRUMENT SOL FFA032 DUE 052198 POC J. Deanna Easley -- 513-487-2027 WEB: Office of Acquisition Management -- Cincinnati Contracts Management Division, http://www.epa.gov/oam/cinn_cmd. The USEPA, National Risk Management Research Laboratory, requires an autosampler instrument to thermally desorb absorbent air sampling tubes of volatile organic compounds and introduce them to a high resolution capillary gas chromatograph. The autosampler instrument must be capable of the following: (1) perform heated dry purge of absorbent tubes to remove water vapor and oxygen prior to thermal desorption; (2) heat absorbent tubes to effect thermal release of absorbed analytes to temperatures as high as 350 C; (3) refocus the desorbed analytes through appropriate water management techniques and/or microscale purge and trap techniques for introduction to 0.32 mm ID capillary chromatographic columns; (4) process at least 16 tubes before reloading tubes; (5) perform all operations under computer control in synchronization with Hewlett-Packard Model 5890 gas chromatographs running under Chemstation control; (6) monitor and report temperature, flow and volume conditions during tube processing; and (7) produce quality assurance reports summarizing conditions during tube processing. All internal surfaces contacting the sample gas stream shall be stainless steel or nickel with minimal use of Teflon. All offerors who can meet the minimum specifications should submit a quote. Quotations may be faxed to D. Easley at 513-487-2107. No telephone requests will be honored. (0126)
