- Description
- This synopsis is being provided to publish a requirement for the Ecosystem Research Division (ERD) of the Environmental Protection Agency?s (EPA), National Exposure Research Laboratory (NERL) in Athens, Georgia which is seeking an experienced vendor to provide and install a fully integrated, computer-controlled, automated, stable isotope ratio preparation and analysis system for natural abundance-level measurements. The system shall provide natural abundance-level measurements of: (1) the stable isotopic compositions of methane (13C/12C), carbon dioxide (13C/12C and 18O/16O), nitrous oxide (15N/14N and 18O/16O), O2 and N2 and also Ar/N2 ratios; (2) the stable oxygen and hydrogen isotopic composition of water; and (3) the stable carbon isotopic composition of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC). A major requirement of the IRMS system is that it be configured for maximum flexibility and efficiency in completing sample analyses and to minimize system downtime. The system should include: (1) one or more continuous flow (CF) isotope ratio mass spectrometers (IRMS); (2) one or more automated, computer-controlled preparation modules for unattended preparation of multiple samples for IRMS analysis; and (3) a computer data system (DS) to control the various components of the stable isotope ratio preparation and analysis system and for data acquisition and manipulation. The system should also interface with our: (1) GV Instruments (formerly Fisons) NA 1500 NC elemental analyzer (EA) to allow automated analysis of stable C and N isotope ratios of bulk organic materials and the stable N isotope ratio of ammonium adsorbed to KHSO4-impregnated filters; (2) our Hewlett Packard (HP) 5890 Series II gas chromatograph (GC)/ GV Instruments (formerly Fisons) Isochrom III combustion system to allow analysis of the 13C/12C of individual peaks eluted from a capillary GC column; and (3) our GV Instruments (formerly Fisons) dual reference gas injector box. The system should also include an EA-diluter to allow sequential stable carbon and nitrogen isotope ratio determination for samples in which N and C compositions differ significantly. Conversion among the various configurations should require one hour or less. The DS should allow export of data to Excel spreadsheet format and report the stable isotopic data in the standard delta notation in parts-per-thousand (?): dHX (?) = [((HX/LX)sample / (HX/LX)standard) - 1] * 1000 where HX/LX is 13C/12C, 15N/14N, D/H, or 18O/16O. The stable isotope ratio preparation and analysis system should be capable of determining highly precise stable isotope ratios of the following components at the listed minimum sample sizes and with stated precision (? one standard deviation): Methane (13C/12C): 0.2 microliters (? 0.3 ?) Nitrous oxide (15N/14N and 18O/16O): 40 nanoliters (? 0.3 ?) Carbon dioxide (13C/12C and 18O/16O): 0.2 microliters (? 0.3 ?) O2 (18O/16O): 10 microliters (? 0.3 ?) N2 (15N/14N): 10 microliters (? 0.3 ?) Water (D/H and 18O/16O): 200 microliters (? 1.5 ? and ? 0.3 ?, respectively) DOC and DIC (13C/12C): 5 micrograms of C (? 0.3 ?) Gas concentration ratios (Ar/N2, Ar/O2, O2/N2): 1 ml of air or headspace (? 0.3 ?) A written solicitation, PR-CI-05-11358, is anticipated to be issued the week of September 12th. It is anticipated the solicitation will be issued as a request for proposal (RFP). All responsible businesses may submit a proposal in response to the solicitation which shall be considered by the Agency. This procurement will be pursued using FAR Part 12 Commercial Acquisition methods and procedures. This notice of intent is not a request for competitive proposals. Additional product details and required specifications will be made available along with the solicitation. The Government will award a contract resulting from this solicitation to the responsible offeror whose offer conforming to the solicitation will be most advantageous to the Government, price and other factors considered. An offer must include the minimum requirements of the Statement of Work (SOW). In addition to price, the following factors will be used to evaluate the offeror?s technical proposal: responsiveness to the PWS, previous experience, past performance, and delivery schedule. Award will be made to the offeror that represents the Best Value. Contract type will be firm fixed price.
