- Description
- Concerns having the ability to furnish the product described herein are requested to give written notification (including the name and telephone number for a point of contact) to the contract specialist listed in the announcement within 15 calendar days from the date of this synopsis. The U.S. Geological Survey requires a spectrofluorometer-phosphorimeter system. This device requires the following: High intensity (450 W), vertically oriented, ozone-free Xenon arc lamp for steady state fluorescence measurements and complementary alternate capability (150 W, ozone-free Xenon flash lamp) for pulsed excitation to provide time-resolved phosphorescence measurements. Both lamps shall be housed together in a dual-lamp housing to provide optimal performance in both fluorescence and phosphorescence modes. Pulse rate and delay for phosphorescence measurements shall be software adjustable to facilitate sensitive, time-resolved, analysis of lanthanide-ligand luminescence (e.g. Eu-ligand luminescence). A double-grating excitation spectrometer with filters to attenuate the xenon bulb power, 1200 groove/mm classically ruled plane grating(s) at 330 nm for excitation, and scanning range from 0 nm to 2000 nm. Stray light discrimination is such that < 1X10-10 is allowed to pass through the excitation spectrometer. A double-grating emission spectrometer with 1200 groves/mm classically ruled plane grating(s) at 500 nm emission and scanning range from 0 nm to 2000 nm. Stray light discrimination is such that < 1X10-10 is allowed to pass through the emission spectrometer. Excitation and emission spectrometers shall provide wavelength accuracy of 0.5 nm and repeatability 0f 0.1 nm Automatic self-calibration of both wavelength-drives and slits Continuously adjustable, computer controlled slits that provide a wavelength bandpass range from 0.3 nm to 30 nm. Optics shall include a separate photodiode reference detector, and automatic excitation shutter, for high measurement stability, and to minimize sample photolysis. Excitation and emission optics shall allow for efficient illumination of sample and emission collection and ensure continuous and focused illumination for all wavelengths without chromatic aberations, to allow for precise illumination of micro or reduced volume samples, and allow for excitation and emission measurements from the far UV to the NIR without changing spectrometer optics or refocusing spectrometer optics The detector shall include a photomultiplier with electronics to reject noise covering the wavelength range between 185-nm and 850 nm, and allow integration times from 0.001 sec to 160 sec, with a signal to noise ratio of >10,000 to 1 (Raman peak of water; (Ex 350 nm, Em 397 nm, each 5 nm band pass, 1 sec integration: to [450 nm-baseline noise]) to allow fast measurement time together with high accuracy and sensitivity. The ability to detect 50 femtomolar (fM) fluorescein A micro-well plate-reader able to accept plates with up to 384 wells and including the 96-well plate format and connected directly to the spectrofluorometer via an optical interface that will allow efficient excitation down to 260 nm facilitating excitation and emission scans and wavelength-paired intensity measurements. The plate-reader shall move the plate through stationary optics to facilitate high sensitivity, accuracy and reproducibility, and available software shall allow custom selection of wells for sample documentation and measurement and data analysis parameters. A thermostatted, fully-automated, 4-position sample changer for holding four, 1 cm x 1 cm optical-path, fluorescence cuvettes; includes magnetic stirring capability. An external thermostatted water bath shall be an optional feature and not required. Shall include a fully Windows compatible software for fully automated control of all instrument functions, including accessories, data collection, data processing, and data export in a format compatible with other windows based applications, such as Microsoft Excel. Based on the information at this time, the government considers the product specified as a sole source from Horiba Scientific and proposes to negotiate a contract with the firm on that basis. However, should additional sources be identified, they will be considered. Firms who feel that they can furnish the required product or its functional equivalent (based on the criteria specified herein) are invited to submit, in writing, an affirmative response to this announcement. An affirmative response would include literature, brochures and other such materials which correspond to the required services and supplies stated herein. This information will be evaluated and used to determine if competitive opportunities exist. Since no solicitation document exists, request for such documents without accompanying information will be considered non-responsive to this request without further consideration. Affirmative response shall be received by this office by close of business August 9, 2012 by 3:00 P.M Mountain Standard Time. This notice may represent the Governments only official notice of this procurement.
