66 -- GC/MS SYSTEM SOL RPOJPLN-3XCKM9 DUE 092698 POC lINDA J. KETCHUM 513-487-2001 WEB: Office of Acquisition Management-Cincinnati Contracts, http://www.epa.gov/oam/cinn_cmd. E-MAIL: Linda J. Ketchum Cincinnati Contracts Management Divisionhtt, Ketchum.Linda@epamail.epa.gov. The US EPA Contracts Management Division in Cincinnati OH is accepting quotes for destination pricing for a Gas Chromatograph/Mass Spectrometer. The system must operate with existing equipment which EPA already has in service. At this time, EPA contemplates a sole source purchase meeting the following specifications to Leco Corporation St. Joseph MI. GC/MS System consisting of: 1. 70 ev electron impact mass spectrometer must be capable of scanning between 25 and 1000 amu. Must also be capable of scanning this full mass range from 1 to 500 scans per second. This fast scanning is required to support the fast GC operations which will be performed using this instrument. 2. Differential pumping capable of supporting up to 5 mL per minute helium flow into the GC/MS system. 3. "Fast GC" system: a. GC with 1 splitless capillary injection port and auto injector; b. gas chromatograph must be fully controllable from computerized data system, must operate from,0 C to 450 C using LN2, temperature setpoint resolution of 1 C or better, and must be capable of temperature programming at 120 C per minute or faster; c. injector must allow electronic control of pressure, flow and split ratio. Must operate at pressures between 0 and 150 psi. 4. Data system consisting of at least a Pentium 300 MHz computer with 5 Gb or larger hard drive. All system software capable of operating system, including the NIST or Wiley special library. See Notes 22 and 26 Posted 08/25/98 (W-SN241549). (0237)
