66 -- READVERTISEMENT OF PYROLYSIS AND ORGANIC CARBON DETERMINATOR INSTRUMENT SOL 9008 DUE 033295 POC Cindy Sather (703-648-7361)(contact)Brian Heath(CO) U.S. Geological Survey is readvertising its IFB requirement (previously appearing in the CBD on June 9, 1994) for the following ''brand name or equal'' pyrolysis and organic carbon determinator instrument. System to be purchased: ROCK-EVAL II manufactured by Humble Instruments of Humble, TX. The contract shall include installation and operator and maintenance training on site in Moscow, Russia. Salient characteristics are: Microprocessor-based instrument using the IFP-FINA process of whole rock pyrolysis equipped with organic carbon module that determines total organic carbon directly by combustion on same sample that is used for the pyrolysis procedure. The autosampler system must be capable of transferring the sample crucibles successively to the pyrolysis oven, then to the oxidation oven (organic carbon determination), and back again to the autosampler carriage. Must be constructed of metal with autosampler that can run 48 samples automatically. Sample containers to be constructed also of metal and will accommodate samples in the 1 to 200 mg range. Microprocessor must have capability for self-diagnosis and trouble shooting of the whole system. Must have built in minimum of 4 pyrolysis cycles. Performs following pyrolysis analysis automatically: volalitization of free hydrocarbons detected by flame- ionization detector, thermal cracking of kerogen during high temperature pyrolysis step, trapping of carbon dioxide produced during pyrolysis with trap shut-off controllable, purge of carbon dioxide trap and determination of carbon dioxide content of samples using a thermal conductivity detector. Unit shall operate on 220V, 50HZ. Installation, spare parts and operable consumable parts kits shall be included. Solicitation No. 9008 is presently available and has a closing date of March 31, 1995. Requests for Solicitation No. 9008 shall be in writing (phone requests will not be honored). Requests may also be made by facsimile to (703) 648-7901 (telephone confirmation is recommended). Previous requests for this solicitation need not be resubmitted. All responsible sources may submit a proposal which shall be considered by the agency. (0045)
