66 -- POWER SUPPLY, RODS AND CONTROLLER SOL NRMGB60235MB DUE 072696 POC Michelle Bernal, 303-497-3983, fax: 303-497-3163 This Procurement is being conducted under simplified acquisition procedures. The National Oceanic & Atmospheric Administration (NOAA) requires a Manual Controller, Cable set, RF Power supply, and set of rods. Specifications as follows: The quadrupole mass filter is to be used to build a chemical ionization mass spectrometer (CIMS) that will perform airborne measurements of very small concentrations of trace gases in the atmosphere. When constructed the CIMS will be flown aboard the NOAA WP-3 Orion aircraft. The mass filter is a key component of this system. The quadrupole mass filter must be a complete system which consists of the following four components: 1)one set of four quadruple rods mounted in a vacuum compatible vented container; (2)RF power supply; (3)Controller electronics which allows both manual and computer controlled mass scans; (4)Cables to connect power supply, controller and mass filter. The four parts of the system described above must be separable in order to be more easily fitted onto an aircraft and must be compatible with the chemical ionization source, a modified flowing afterglow that has to be developed for this application. Requirements as follows: (1)Mass range - 10-300 amu or greater. (2)Mass scan Rate - )600 amu/s. (3)Quadruple rod diameter - must be 0.75 inches or greater. (4)Power - both the RF power supply and control electronics must have the capability to be powered by only DC voltages. (5)Resolution - )250 at 4 amu. (6)Modular design - The system must be of modular design in order to be more easily fitted onto an aircraft. In addition, it must be compatible with the chemical ionization source, a modified flowing afterglow, that has to be developed for this application. The National Oceanic & Atmospheric Administration (NOAA) proposes to negotiate on a sole source basis with ABB Extrel Corporation of Pittsburgh, PA. In the event there are other qualified sources interested in proposing to supply an equivalent unit must submit a written quote establishing capability to meet the above requirements within 15 days from the date of synopsis. There will be NO formal RFQ. (0185)
