Description

The National Institutes of Health (NIH), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has a requirement to purchase a 5mm Balun NMR Probe for a Wide-Bore 600 MHz Spectrometer and a 5mm MAS Rotor Starter kit from Varian Inc., 3120 Hansen Way, Palo Alto, CA 94304. The specifications shall be included in the following system: 1) The probe must be compatible with the dimensions and field strength of an existing Oxford Instruments wide-bore 14.1 Tesla magnet, serial number DLN1800, with 26-channel Oxford Instruments room temperature shims; 2) The probe must be compatible with the hardware and software for control of sample spinning rates and sample temperature in an existing Varian NMR Systems Infinity spectrometer, serial number 3484; 3) The probe design must permit changing of frozen samples at low temperatures without any need to warm up the probe or samples during sample changes and without accumulation of ice that interferes with sample spinning; 4) Samples volumes must be 160 microliters; 5) NMR measurements in the temperature range from -150C to +50 C must be possible; 6) Sample spinning rates up to at least 12 kilohertz must be possible, with stability better than 0.5 parts per thousand; 7) The radio frequency circuitry within the probe must be balanced to minimize radio frequency field inhomogeneity and arcing at high voltages; 8) The probe must operate in double-resonance (proton and carbon-13) and triple-resonance (proton, carbon-13, and nitrogen-15) modes. In triple-resonance mode, the probe must achieve radio frequency field strengths of 74 kHz or higher for at least 43 milliseconds on the proton channel, 73 kHz or higher for at least 10 milliseconds on the carbon-13 channel, and 50 kHz or higher for at least 10 milliseconds on the nitrogen-15 channel. In double-resonance mode, the probe must achieve radio frequency field strengths of 79 kHz or higher for at least 43 milliseconds on the proton channel and 78 kHz or higher for at least 10 milliseconds on the carbon-13 channel. These specifications must be achieved with power levels of 500 watts or less on the proton channel, 550 watts or less on the carbon-13 channel, and 750 watts or less on the nitrogen-15 channel; 9) Carbon-13 detection sensitivity, measured on the methyl carbon signal from 180 milligrams of unlabeled hexamethylbenzene at 3.3 kHz spinning speed in four scans, must be at least 446:1 in double-resonance mode and 297:1 in triple-resonance mode. Nitrogen-15 detection sensitivity, measured on 160 milligrams of unlabeled glycine at 3.3 kHz spinning speed in 64 scans, must be at least 100:1 in triple-resonance mode; 10) The probe must include five zirconia rotor sleeves, seven drive tips, eleven top and bottom spacers, and tools for sample packing and removal of drive tips and spacers. The Institute intends to purchase this equipment by other than full and open competition from Varian, Incorporated. To the best of the Governments knowledge they are the sole manufacturer and distributor of this equipment. Interested vendors may identify in writing their interest with a capability statement to the Contracting Office prior to the closing date of this notice. This notice of intent is not a request for competitive proposals, however, all responses received, before the closing date, of this announcement will be considered by the Government. A determination by the Government not to compete this proposed acquisition is based upon responses to this notice and is solely within the discretion of the Government. Information received will be considered solely for the purpose of determining whether to conduct a competitive procurement. This notice is for the purchase of commercial equipment with the Simplified Acquisition Threshold of up to $5 million dollars. It is anticipated that Request for Quotation (RFQ) NIH-NIDDK-02-793 will be available fifteen (15) days after the publication date of this synopsis. This Request for Quote (RFQ) will be issued on August 16, 2002. Receipt of quotations will be due ten (10) days after the release of the RFQ (August 26, 2002) The anticipated award date is August 30, 2002. Request for copies of the RFQ must be in writing and may be FAXED to 301-480-4226. Quotations must be submitted in writing to the National Institute of Diabetes and Digestive and Kidney Diseases 6707 Democracy Blvd., Room 774C, Bethesda, Maryland 20817 Attention: Patricia Haun. FAX quotations must contain offerors names, address, telephone number and fax number. FAX quotations will only be accepted if dated and signed by an authorized company representative.
