66 -- LABORATORY EQUIPMENT POC Kevin Merriweather, 202-927-7716 The Bureau of Alcohol, Tobacco & Firearms (ATF) has a requirement for the purchase of 1 EA: High performance electron ionization GC/MS/MS system complete with integrated gas chromatograph (GC). Two electronic pressure controlled injectors (one split/splitless and one temperature programmed split/splitless) installed in GC. Vacuum system pumped by 180 1/sec air cooled diffusion pump. Mass analyzer comprised of a quadruple ion trap with mass range 10 -- 1000U at unit resolution across mass range when scanning at greater than 10,000u/second. High efficiency ion source external to ion trap using replaceable ion volumes for rapid interchange (less than 5 minutes) between El and Cl. Solids -- probe inlet system through an integrated interlock also used for ion volume insertion and removal. Solids probe is inserted into MS without GC removal or otherwise changing GC. Source design featuring plug-in filament cartridges. Ultra- SIM capability allowing user -- selected multiple ion monitoring which is changeable scan to scan. Positive and negative ions detected by ceramic cartridge plug-in electron multiplier with +/- 15kV conversion dynode and zero noise detection electronics. Self contained ion gauge with integrated output for data system display and recording of operational pressures. Gateway 2000 data system with 120MHZ pentium CPU. ISA/PCI bus, 16mb memory, 1.6GB IDE disk drive, 3.5" diskette drive, 8x cd-rom, 15" super VGA high resolution color monitor, mouse and Microsoft operating system. DS includes full GC/MS control and data analysis package. A200s autosampler with 1.5ml x 105 vial sample tray. NIST 62,000 non-duplicate and 12,000 additional duplicate compound mass spectral library on cd-rom. GC/MS sensitivity (El) splitless injection of 10 pg of decafluorobenzophenone produces S/N at least 25:1 when a full spectrum from 60 -- 400u is continuously acquired with 0.5 second cycle time. (Pos Cl) Splitless injection of 100 pg DFBP, S/N for (M+H) at m/z 363 is at least 10:1 for m/z 60 -- 400 scan with 0.5 second cycle time. (M+29) must be observable. (NlCl) 1 pg DFBP S/N for M -- is at least 50:1 for 60 -- 400u scan with 0.5 second cycle time. MS/MS:100 pg DFPB by Pos Cl GC/MS produces S/N 10:1 for 195 production at M/Z 363 in production mode scanned 100 -- 400u in 0.5 second. Full demonstration of specifications shall be given prior to award. 90 day warranty on all items required. Simplified Acquisition Procedures will be used for this requirement. All quotes must be received with 15 days of the publication date of this notice. No RFQ is available for this requirement. Basis for award will be ability to meet specified requirements at a price that is determined to be fair and reasonable. Awardee must complete an SF3381, ACH Vendor/ Miscellaneous Payment Enrollment form, for payment via electronic funds transfer.***** (0247)
