66 -- APCI UPGRADE TO FINNIGAN MAT TSQ 700 SOL 5114-6-3023 DUE 083096 POC Lori J. Houghton, Contract Specialist, (309) 681-6616 The U. S. Department of Agriculture, Agricultural Research Service, MidwestArea has a requirement to purchase an APCI Upgrade for a Finnigan MAT TSQ 700 Mass Spectrometer for the National Center for Agricultural Utilization Research. This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. Solicitation No. 5114-6-3023 is being issued as a Request for Quotation. This solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 90-38. This solicitation is unrestricted. In order to use this mass spectrometer for our ongoing research into the structural characterization of fats and oils from plant and animal sources, the mass spectrometer must be fitted with an ionization source which uses atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) techniques. CLIN 0001 Field installed APCI and ESI control electronics and software for TSQ700/7000 systems. Includes electronic control module and interfacing cables with software control. ESI/APCI head control electronics included. Requires revision 7.0 or higher ICIS software and downloadable firmware. Included installation. Requires APCI and ESI hardware, 1 each. CLIN 0002 Shipping for CLIN 0001. CLIN 0003 Field installed APCI/ESI hardware for TSQ700/7000. Includes APCI head and loop injector. Mounting hardware and installation included. Requires APCI and ESI electronics and software, 1 each. CLIN 0004 Shipping for CLIN 0003. The criteria which must be satisfied by a suitable APCI/ESI ionization source upgrade are given as the following salient characteristics: The upgrade must perform atmospheric pressure chemical ionization and electrospray ionization on a Finnigan MAT TSQ 700 mass spectrometer. The upgrade must be compatible with ICIS Software Revision 7.0, which acts as the instrument control, data acquisition, and data analysis system on the Finnigan MAT TSQ 700 mass spectrometer. The upgrade must have electronics which can be controlled by the instrument control portion of ICIS Software Revision 7.0 to provide settings of vaporizer temperature, corona current, sheath and auxiliary gas controls for APCI ionization mode, and nozzle current and sheath and auxiliary gas controls for ESI ionization mode. Selection of ionization mode must be software controlled using existing ICIS 7.0 Software, or an appropriately updated software revision. The upgrade must include an electronics module which will provide voltage sources and adjustment electronics which give adjustable vaporizer heater control, adjustable corona current control, adjustable capillary heater control, and on/off gas solenoid controls for APCI ionization mode, and adjustable nozzle current control and on/off gas solenoid controls for ESI ionization mode. The upgrade must include the following hardware: 1) a vacuum housing which is fully compatible with the existing vacuum housing on the Finnigan MAT TSQ 700 mass spectrometer, 2) ion lenses in the new vacuum housing to replace the ion lenses used by the conventional ionization source, 3) a capillary bleed to act as the interface between the atmospheric pressure region of the source and the high vacuum quadruple region, 4) an APCI ionization head which contains several basic components: a vaporizer heater, a corona discharge needle for ionization, sheath and auxiliary gases for HPLC eluent desolvation, 5) sheath gas and auxiliary gas control solenoids, 6) a sample loop injector for use with HPLC flow systems, 7) the option to add an ESI ionization head at a future date, 8) all cables and gas lines necessary to operate the above mentioned controls. The upgrade must include all ion lens control electronics which are fully compatible with existing ion lens controls. The upgrade may utilize existing voltage sources and electronics if modifications are made by a qualified electronics technician which will make those existing lens controls compatible with ion lenses used in the APCI/ESI vacuum housing. The APCI/ESI upgrade should be capable of handling HPLC effluent flow rates up to 2.0 mL/min. The upgrade should be capable of using HPLC effluent flow rates at low as 0.050 mL/min. Delivery to be within 120 days ARO. FAR 52.212-1 Instructions to Offerors - Commercial, FAR 52.212-2 Evaluation - Commercial Items, FAR 52.212-3 Offeror Representations and Certifications - Commercial Items, and FAR 52.212-4 Contract Terms and Conditions - Commercial Items apply to this acquisition. Quotations will be evaluated on price and price related factors. Offers are to be received Not Later than the close of business, August 30, 1996 at USDA-ARS-MWA, Contracting Office, 1815 N. University Street, Peoria IL 61604. The POC for this acquisition is Lori Houghton, (309) 681-6616. (0219)
