66 -- GAS CHROMATOGRAPH HIGH RESOLUTION, MASS SPECTROMETER COMBINATION SOL 52SBNB5C8706 POC Shirley Shoemaker (301) 975-6334 17. The National Institute of Standards and Technology (NIST) has a requirement to purchase a state of the art current production model gas chromatograph high resolution mass spectrometer combination. A data system which controls the instrument and provides for data acquisition and processing shall be an integral part of the system. The following represents a portion of the system requirements that shall provide: (1) high vacuum regions pumped by turbomolecular pumps which are protected by splinter shields and isolated from the instrument by vibration dampers (compensators), (2) a Hewlett-Packard 6890 Series Gas Chromatograph and Automatic Liquid Sampler or EQUAL, (3) an ion detector suitable for the detection of both positive and negative high mass ions, (4) an accelerating voltage that is adjustable either continuously or in 1 kV steps from 2 kV to the full accelerating voltage, (5) a mass range including at least m/z 2-2400 at full accelerating voltage, (6) a minimum cycle time for a magnetic scan over the mass range of m/z 50-500 that shall not exceed 0.2 sec at a resolution of 1,000 (10 percent valley), (7) a temperature of the ion source controlled up to at least 350 degrees Centigrade, (8) a static resolution of at least 60,000 (10 percent valley definition), and (9) a resolution of at least 600 for product ion spectra obtained with the collision cell in the first field free region. The data system shall include at least a Hewlett-Packard Workstation 715, Digital Equipment Corporation Workstation Alpha 3000 or EQUAL, an acquisition processor including one or more microprocessors for instrument control and data acquisition, magnetic disk storage with a capacity of at least one GB, magneto-optical disk and/or streaming tape for archiving of at least one GB capacity, network capability, and two color monitors of 19 inch diagonal measure. The contractor shall provide: (1) source code for all operations, complete documentation for hardware and software, including routine maintenance and repair information, and operating manuals, (2) one- year warranty on parts and labor, (3) on-site operator training, and (4) on-site survey of the intended installation site. The contract also includes options to purchase: (1) an ion gauge on both the ion source and analyzer regions or preferably on each separately pumped region, (2) a second ion source, (3) all necessary components for fast atom or cesium ion bombardment (FAB), (4) a direct exposure probe, (5) a substitute for the data archiving, (6) frit-FAB and electrospray, (7) color monitors of a diagonal measurement of at least 21 inches, and (8) software for use on IBM compatible and Macintosh personal computers which allow computers to be connected to the data system and to emulate a terminal. The contractor shall make delivery 180 days after date of contract. Proposals will be evaluated on the contractor's ability to meet the specifications, experience, and price. It is estimated that the solicitation will be released during May/June 1995. The Standard Industrial Code is 3826. Requests for the solicitation may be requested by mail at the above address or via FAX number 301-963-7732. (0088)
