66 -- ISOTOPE RATIO MASS SPECTROMETER SOL RFQ-97-R-03 POC Raoul D. Scott Jr., 513-366-2071 E-MAIL: Contracting Officer's Email Address, scott.raoul@epamail.epa.gov. The U.S. EPA National Risk Management Research Laboratory requires the use of any isotope ratio mass spectrometer (IRMS). The initial applications for the IRMS in our laboratory will focus on both natural and enriched carbon and nitrogen isotopic compositions of individual peaks resolved by gas chromatography from environmental and laboratory generated samples. The samples can include gas, liquid, or solids for analysis. Examples of species of interest are nitrate, bicarbonate, methane, carbon dioxide, nitrogen, nitrous oxide, and complex organic compounds such as petroleum, pesticides, or explosives. The system will interface a gas chromatograph (GC) with the IRMS via combustion interface in tandem with a bench top mass spectrometer to allow detection and identification of peaks eluting from the GC. The elemental analyzer portion of the system will be used to prepare samples not suitable for GC analysis. The total system must be capable of simultaneous acquisition of isotopic analysis and compound identification by electron impact or chemical ionization mass spectrometry. The system should be capable of operating over a wide range of isotopic abundances from naturally occurring to enrichments on the order of several atom percent. A computer data system will control the various components and provide fro data acquisition and manipulation. The solicitation will be processed as a commercial item using FAR Part 12 procedures. It is anticipated that the solicitation shall be issued on 6/05/97 with proposals due on 06/23/97. All requests for the solicitation 97-R-03 must be in writing, telephone requests will not be honored. You may fax your request to the Contracting Officer at 513-366-2004. (0148)
