B -- MASS SPECTRA OF PHOSPHORUS COMPOUNDS IN COMPLEX MATRICES SOL 52SBNB7C1072 DUE 032897 POC Contract Specialist,Kathleen Lettofsky (301)975-6342,Contracting Officer, Lisa K. Jandovitz (301)975-6344 WEB: NIST Contracts Homepage, http:www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@mailserver3.nist.gov. The National Institute of Standards and Technology (NIST) Mass Spectral Data Center of the Physical and Chemical Properties Division is developing a set of gas chromatography -mass spectral (GC/MS)data for use in evaluating the source of phosphorus compounds in complex GC/MS data files. NIST intends to acquire the services of a contractor to perform a series of experiments and undertake preliminary analysis of the results. The experiments include, but are not limited to: 1) GC/MS analysis of simple (solvent + analyte) mixtures of phosphorus containing compounds; 2) GC/MS analysis of simple (solvent + derivitized analyte) mixtures resulting from the derivatization of organic acids and alcohols containing phosphorus using N.N-bis-(trimethylsilyl) trifluoroacetamide (BSTFA); and 3) GC/MS analysis of complex mixtures of derivatized samples of natural origin. The minimum number of analyses for the three prior items is 500, 200 and 100 respectively for the base year and two option years. The minimum monthly delivery of spectra for the three prior items is 25,10 and 5 for the base year and two option years. The maximum number of analyses for the three prior items is 1000, 500 and 250 respectively for the base year and two option years. NIST also requires quality assurance/quality control be performed before any experiments each day by the contractor. In addition, before and after any changes in the system are made, the same QA/QC run shall be performed. The QA/QC run shall consist of an injection of a standard solution specified by NIST. For all analysis experiments, as well as for all QA/QC runs, the full data file shall be supplied to NIST. In addition, NIST may be interested in receiving proposals for additional experiments that would provide a larger database of GC/MS analysis that would aid in identifying phosphorus compounds. The period of performance is anticipated to be for a base year and two option years. All responsible sources may submit a proposal which shall be considered. Only written requests for copies of the solicitation shall be honored. Requests of copies of the solicitation may be telefaxed to (301)963-7732. See Numbered Note 26. (0045)
