66 -- MICROBORE, HIGH PERFORMANCE, LIQUID CHROMATOGRAPHY/TANDEM QUADRUPOLE/TIME-OF-FLIGHT MASS SPECTROMETER SYSTEM SOL ORD #21 DUE 030599 POC Hans Schellhas or Marie Nichols WEB: na, na. E-MAIL: na, schellhas.hans@epamail.epa.gov or nichols.marie@epamail.epa.gov. Under the authority of FAR 6.302-1, the U.S. Environmental Protection Agency intends to negotiate on a sole source basis with Micromass, Inc., for the acquisition of a microbore, high performance, liquid chromatography/tandem quadrupole/time-of-flight mass spectrometer system. This system will be used for the analysis of chemical contaminants in the aquatic environment, and their photolysis, hydrolysis, and metabolic breakdown products including those covalently and non-covalently bound to biomolecules such as protein and DNA. The Government's minimum requirements for this system are as follows: (A) a liquid chromatograph capable of gradient microbore programming with auto sampling and photodiode array analyte detection; (B) a mass analyzer with scientific performance functions to include: (1) receiving liquid chromatographic effluent between 1 and 1000 uL/min for electrospray ionization, (2) an electrospray ionization system capable of sustained analyses while receiving liquids containing salt bufferssuch as phosphate and acetate at 1-25mM, (3) a mass range of 10,000 amu, (4) mass resolution of at least 5000 at 1000 amu, (5) mass measuring accuracy of at least 5ppm at 1000 amu, (6) the ability to analyze both positive and negative ions, and (7) the ability to produce product ion spectra; and (C) a data system capable of controlling both the liquid chromatograph and the mass spectrometer and processing all data both for qualitative identification, as well as quantification of analytes from both the photodiode array detector and the mass spectrometer. This acquisition shall include at a minimum: (1) the computer controlled liquid chromatograph/mass spectrometer system; (2) installation of the instrument; (3) on-site training; (4) consumable supplies; (5) warranty requirements; (6) operation and service manuals; and (7) an on-site preventative maintenance visit at the end of the warranty period. THIS IS NOT A REQUEST FOR PROPOSALS. This acquisition will be accomplished under FAR Part 12, Acquisition of Commercial Items. Only sources capable of fully meeting the unique technical performance specifications/capabilities outlined above, without exception, will be considered. A determination by the Government not to compete this acquisition is solely the discretion of the Government. Technical documentation must be submitted within 15 days of the publication of this notice to the office identified above. The points of contact are Hans Schellhas at (513) 487-2055 or Marie Nichols at (513) 487-2054. The subject facsimile number is (513) 487-2109. Posted 02/18/99 (W-SN299858). (0049)
