R -- MANAGEMENT OF NIST, MASS SPECTROSCOPIC DATA INTO NIST'S MASS SPECTRAL DATABASE SOL 52SBNB9C1049 POC Diane Loeb, Contract Specialist (301) 975-6399 or Sandra Febach, Contracting Officer (301) 975-6326 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) Mass Spectral Data Center (MSDC) seeks to acquire mass spectral data in areas of need in the NIST Mass Spectral database. Specifically, spectral data for O-silyl, N-acyl, and methyl derivatives of mono- and poly- functional compounds are sought. These spectra need to be measured using a Gas Chromatograph/Mass Spectrometer (GC/MS) and must reference quality mass spectra. The mass spectra shall be sent to NIST in both electronic and hard copy forms. The Chemical Abstracts Service registry number shall be included if available, as well as the chemical name and a hard copy of the chemical structure. The contractor shall measure a minimum of 500 up to a maximum of 2000 mass spectra per year. The total number of spectra to be measured for the base and option periods shall not exceed 6000. NIST requires delivery of a minimum of 40 measured spectra per calendar month. The National Institute of Standards and Technology (NIST) Mass Spectral Data Center (MSDC) is receiving a steady influx of new spectra that need to be evaluated before being added to the NIST Mass Spectral Database. This evaluation needs to be done in a timely and efficient manner. The contractor shall evaluate the quality of reported mass spectra by using the structure for the compound and known good spectra of similar compounds. The evaluation shall involve determining that the mass spectrum of a compound with a given structure is reasonable by using probable losses from the molecular ion and well established rearrangements of ions with corresponding neutral losses from the structure of the presumed starting compound. The evaluation shall require the ability to assess the possibility of contamination either by air, water, isomers, or other species that may coelute in gas-chromatography columns. In addition, the evaluation shall require the ability to evaluate the probability of thermal decomposition of the molecule in the ion-source of the mass spectrometer and an understanding of the ions resulting from species that have no stable ions. NIST shall provide to the contractor copies of the spectra to be evaluated along with the names and chemical structure of the presumed starting compounds. These shall be provided either in the form of paper copies of the spectra or electronic files. In order to read the electronic files a copy of the NIST/EPA/NIH Mass Spectral Database shall be made available to the contractor. The contractor shall have experience in examining both good and bad spectra. The minimum qualifications of personnel to perform this work include, but are not limited to, a degree in chemistry and at least two years of experience analyzing and evaluating mass spectra data. Experience with routine mass spectra analysis is not sufficient for this purpose. Published papers showing research in correlating spectra to structure or documented prior experience with such correlations shall be provided. NIST shall deliver a minimum of 5000 up to a maximum of 18000 mass spectra per year with the associated structures that should be analyzed. The total number of spectra to be analyzed for the base and option periods shall not exceed 54000. NIST shall deliver a minimum of 400 spectra per month for evaluation. NIST requires delivery of the analysis no later than 45 calendar days following the receipt of the spectra and structures from NIST. The period of performance for this contract is a base year period with two option year periods. All deliverables shall be FOB Destination, Gaithersburg, MD. The standard industrial classification (SIC) code is 7389 and the small business size standard is $18 million dollars. All responsible small business sources may submit a proposal which shall be considered by the agency. Interested firms may receive a copy of the RFP by writing to the National Institute of Standards and Technology, Acquisition and Assistance Division, Building 301, Room B117, 100 Bureau Drive, Stop 3572, Gaithersburg, MD 20899-3572, Reference 52SBNB9C1049, or request by fax number (301) 963-7732.
