Description

The National Institutes of Health (NIH), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has a requirement to purchase an Infinityplus 3rd RF Channel, 20-480 MHz from Varian Inc., 3120 Hansen Way, Palo Alto, CA 94304. The technical specifications shall be included: 1) The channel must cover the frequency range from at least 28 Megahertz to 162 Megahertz, corresponding to NMR frequencies of nitrogen-14 and phosphorus-31 nuclei. 2) The pulse programmer for this channel must permit the application of pulse sequences of significant complexity (at least 1024 pulse sequence steps), including conditional execution of pulse sequence blocks, nested loopoing with at least ten different loop counters, independent phase cycling or phase incrementation of all radio frequency pulses and amplitude modulation of individual pulses. This pulse programmer should be identical to the pulse programmers for the existing channels. 3) Shall be able to trigger radio frequency pulses on the third channel explicitly and actively from an external logic signal, for example, from a sample spinning speed tachometer in order to synchronize pulse sequences with sample spinning. This external triggering capability is absolutely essential for many experiments to be performed with the new spectrometer console, and must be absolutely reliable with no jitter or instability in synchronization above 100 nanoseconds. 4) The channel must include digital phase-shifting in increments of 0.35 degrees (10 bits) or less. Small-angle and large angle phase shifts must occur in less than 100 nanoseconds (to 90% of desired phase change) from the time at which the phase shift is requested by the pulse program. There should be no software or hardware delays that limit phase switching times to more than 100 nanoseconds. Inaccuracies in phase shifts must be less than 0.1 degrees. For a fixed amplitude setting in the pulse program, the pulse amplitude must be independent of phase without any requirement for manual adjustment or calibration by the user. 5) Amplitude modulation of radio frequency pulses must be possible on the channel, with arbitrary shape specified in the pulse program, over an amplitude range of at least 60 dB. Amplitude switching by 20 dB must occur in less than 100 nanoseconds (to 90% of desired amplitude change) from the time at which the amplitude change is requested by the pulse program. 6) Apply pulse sequences asynchronously from the other two existing channels, for example, as in heteronuclear pulse decoupling or TPPM decoupling experiments. It must be possible to program the spectrometer so that the timing of pulses and delays on the third channel is not dependent on the timing of pulses and delays on the other two channels, so that pulse lengths and delay lengths can be set arbitrarily and independently on the third channel. 7) Must be compatible with the Varian Infinity Plus NMR Spectrometer. The Institutes intends to purchase this equipment by other than full and open competition from Varian Inc. To the best of the Government's 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 Officer 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. It is anticipated that Request for Quotation (RFQ) NIH-NIDDK-02-735 will be available fifteen (15) days after the publication date of this synopsis. Receipt of quotations will be due ten (10 days after the release of the RFQ. The anticipated award date is April 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 Institutes 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.
