66 -- OPTICAL BENCH SPECTROPHOMETER SOL 9932NR-145 DUE 071399 POC Leon Dodson 301/504-8445 This is a combinded synopsis/solicitation for commerical items prepared in accordance with FAR subpart 12.6 as supplemented with additional information included in this notice. The announcement constitutes the only solicitation ; proposals are being requested and a written solicitation will not be issued. The solicitation number 99-32NR-145 is issued as a Request for Quotation (RFQ), and incorporates provisions and clauses that in effect through Federal Acquisition circular 90 -- 46. The standard industrial classification code is 6640. Delivery is required on or about July 30, 1999 or within 30 days after award. Delivery is FOB destination to USDA,ARS,BA,NRI,ISL Bldg 303, Powder Mill Road East, Beltsville, MD 20705 Quotation should be addressed to USDA, ARS, BA, NRI Admin. Office, Bldg. 003, Rm. 218, BARC-West, Beltsville, Md 20705 Attn: Leon Dodson Jr. The proposed contract will include the following: Item 01, FT-IR Spectrometer to include inside delivery, set-up, training and 5 yr warranty Descriptive literature showing that the quoted FT-IR SPECTROMETER meets all specifications included herein mjust accomany the quotation. This system should consist of a Fourier-Transform Infrared Spectrometer (FT-IR), FT-Raman module, experimental sample accessories, and associated software as descibed below: (1)FT-IR Spectrometer. The FT-IR spectrometer must be high perfomance, optically flexible, rugged and user serviceable. The instrument is to be operated using vendor supplied software on a PC computer. The instrument as delivered must be able to accommodate applications in raman, mid-and near infrared spectroscopy. 1The interferometer must be capable of achieving resolution of better than 0.1251/cm meassured full with at half height (FWHH). Automatic interferometer alignment necessary for perodic system optimization and spectral range changeover must be under complete computer control. 2 The standard spectral range must be 11, 000 to 400/cm without changing the interferometer, beamsplitter and detector.3 Detector selector must be completely automated and accessed via software control. 4 The system must be able to accommodate simultaneously mounted sources for both mid-andnear-IR operation. The source must be high intensity and air cooled to eliminate the need for water supplies or recirculators. 5 The system must be capable of collecting a minimum of 35 scans/sec at a resolution of 16 1/cm(8 1/cm data point spacing) wiuth interferograms written directly to the hard disk of the PC. 6 The spectrometer must carry a five year warranty on all interferometer components. 7 The main sample compartment must provide a pinned in place removable baseplate to facilitate experimental set up and easy intercahnge of sampling accessories. The sample chamber must posses purge shutters to prevent loss of purge from the spectrometer. The sample compartment must provide an electronic control bus to permit the installation of an optional accessory. 8 a real time display of a fully ratioed spectrum at full resolution is requiredduring data collection. True multitasking in which searching, plotting, word processing, data collection etc., can be performed simultaneously is required. 9 The spectrometer and software must be capble of automatically identifying when an accessory has been placed or moved from the main sample compartment. 10The insrtument must be completely sealed and desiccated to protect the hydroscopic optical components. (2) Raman Module for FT-IR Spectrometer 1 The excitation laser must be powered by laser diodes to provide 1064 nm excitation, for maximum fluorescence rejection. The power at the sample should be continually variable in the range 0-1.5W, which should be software controlled. The output of the laser should be single mode and has an extremely high stability (<0.05%rms noise flutuations) in order to obtain a high signal-to-noise of the FT-Raman spectrum. The laser is air-cooled and does not require any other ecternal cooling. 2 It should be possibly to fit a high-sensitivity Room Temperature InGaAs detector in the FT-IR instrument. Switching between FT-Raman and FT-IR detector should be computer software controlled, requiring no mechanical changes. 3 A 180 degree reflective geometry should be available. Positioning of the sample in the focus of the laser beam should controlled from the software. (3) ATR Accessory This accessory should be set in FT-IR sample compartment. It should be "point-to-point" contact sample and crystal for solid, gel and powder samples. It has a spectal range of 4000 -- 650 1/cm. The accessory also should be complewtely purgeable,alignment easliy and baseplate configured to bench for maximum reproduciblity. And Complete with standard software with the system.. The Government will award a contract resulting from this solicitation to the responsive/responsible offeror whose offer conforms to the solicitation and is most advantagous to the government. Any interested/qualified source who belives thay can provide the required equipment mus t respond by 3 p.m. on or before July 13, 1999. All such responses will be evaluated in order to determine the ability to meet the above stated capabilities.
