66 -- STABLE ISOTOPE RATIO MASS SPECTROMETER SOL 99WRSS0018 DUE 090899 POC Phyllis Michel, Contracting Officer, (650) 329-4163 or fax (650) 329-5480 E-MAIL: to contact the contracting officer by e-mail, pmichel@wr.usgs.gov. THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. This is Request for Proposals No. 99WRSS0018. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular No. 97-13. This acquisition is non-restricted. Standard Industrial Classification Code is 3826, small business size standard is 500 employees. CONTRACT LINE ITEM: Stable Isotope Ratio Mass Spectrometer, automated dual inlet/continuous flow, and associated peripherals, quantity 1 or 2 systems. DESCRIPTION: The mass spectrometer(s) will mainly be used be for the automated analysis of water samples for O and H isotopes, and automated analysis of gases prepared off-line for for C, N, S, O, and H isotopes. Both instruments will have the following features: dual micro-inlet with cryo-trapping cold fingers for CO2 and N2; electromagnet; analyzer with collectors for the analysis of H2, CO2, CO, O2, N2, and SO2; H/D energy filter for continuous-flow operation; at least 10 multi-ports with removable tube crackers; multitasking Windows/NT operating system; external precision of <0.05 permil for CO2-18O and <0.5 permil for H2 for dual-inlet analysis; and automated water equilibration device for analyzing waters for O and H isotopes using the CO2-H20 and H2-H2O equilibration methods with documented external precisions of <0.1 permil for O and <1.0 permil for H for 200 uL samples of H2O analyzed by continuous flow. Specifications for sensitivity, linearity, and stability must be quoted and demonstrated for both conventional dual inlet and continuous flow modes; all diagnostic tests should be supported by software. This equilibration device will also be capable of analyzing equilbrated carbonates and gas samples for C-O isotopes with precisions of <0.1 permil. In addition, the instruments shall accommodate a customer-supplied Elemental Analyzer for C, N, O, S, and H isotope determinations in organic materials, and have the option to fit up to 8 collectors and acquire data from up to 8 ion beams simultaneously during a run. The operating system will have the ability and flexibility to change operating conditions and experimental procedures on a per sample and per run basis using menu-driven software and macro-programming language. The ability and flexibility of the multi-tasking hardware and software will allow for different operations such as sample analysis, report generation, off-line recalibration and recalculation of isotope ratios, keyboard data entry, or other software programs to proceed concurrently during an analysis. All system components must be totally Year 2000 compliant. DELIVERY: FOB Destination to U.S. Geological Survey, Water Resources Div., Isotope Lab, 345 Middlefield Road, Bldg. 15, Menlo Park, CA. Offerors shall prepare proposals in accordance with FAR 52.212-1, Instructions to Offerors-Commercial Items, and include completed FAR 52.212-3, Offeror Representations and Certifications-Commercial Items. AWARD: Purchase of the second instrument is subject to availability of funds. Offerors shall propose to provide both mass spectrometers. Split awards will not be considered if funds for both instruments are available. The successful offeror will supply all computers, data systems, software, manuals, spare parts, training, shipping, installation, and power supplies necessary for full operation of both instruments. Compliance with specifications must be documented by submission of technical literature or other definitive proof. FAR 52.212-2, Evaluation-Commercial Items, is applicable; the evaluation factors are (a) technical capability of the item offered to meet the Government requirement, (b) nature and extent of documentation of the precision, accuracy, and reliability of the instrument in the form of published reports and technical notes, (c) length and history of manufacturer support for the instrument, and the ease, speed, and location of service engineers and spare parts, and (d) price. Proposals should include proposed delivery schedule and commercial warranty information. FAR 52.212-4, Contract Terms and Conditions-Commercial Items, is applicable, with addendum: FAR 52.204-6, Data Universal Numbering System (DUNS) Number. FAR 52.212-5, Contract Terms and Conditions Required to Implement Statutes or Executive Orders-Commercial Items, is applicable, including the following additional clauses cited therein: 52.203-6, 52.219-8, 52.222-36, 52.222-21, 52.222-26, 52.222-35, 52.222-37, and 52.225-3. NOTICE: Funds are not presently available for this acquisition. Award will only be made if and when funds are made available to the USGS. Proposals shall be mailed to the contracting officer at the address above so as to arrive by 3:00 pm PDT, September 8, 1999. Facsimile and email responses are not acceptable. Posted 08/11/99 (W-SN366676). (0223)
