66 -- MASS SPECTROMETER POC Sharon M. McDowell (703) 648-7375 The U.S. Geological Survey (USGS) is requesting information from commercial sources regarding commercially available mass spectrometers which are equal to the Finnigan MAT 252; with MEMCO 6 Faraday collectors for isotopic analysis of CO2, N2, SO2, O2, and CO2; with electronics for collection of up to six channels simultaneously collected; Dual viscous inlet system including changeover valve and spare membrane and stamps for entire change over valve; Differential pumping; Conflow-III interface for CE elemental analyzers and Finnigan TC/EAs; Tee fittings and two crimps at source to allow USGS to connect one additional 1/16-inch (dual-inlet) sample capillary and on additional 1/16-inch (dual-inlet) standard capillary to mass spectrometer for introduction of gas from USGS mercury pistons instead of bellows; five filaments; multiport (12X) inlet system; source constructed of materials for low memory of oxygen gas. For dual-inlet analyses, the internal precision must be 0.02 per mill or better. Data acquisition and control software must be compatible with LIMS for Light Stable Isotopes (U.S. Geological Survey Open-File Report 98-284). Based on information available at this time, the USGS considers the required system to be sole-source and plans to enter into non-competitive discussions with Finnigan MAT of San Jose, California. Any responses to this synopsis should contain sufficient technical documentation and descriptive literature to sufficiently describe system capabilities. Publicly available commercial pricing information in response to the above description is also requested in as much detail as possible. Neither a draft statement of work nor specifications are available. The Government will not pay for information provided in response to this synopsis. The Contracting Officer plans to acquire the software and related services pursuant to FAR Subpart 13.5 -- Test Program for Certain Commercial Items. Technical and commercial price information responding to this request should be received by close of business on September 10, 1999. Posted 08/31/99 (W-SN374775). (0243)
