for a 400 MHz NMR system. Southern Illinois University Carbondale is seeking bids for a NMR system to meet the following minimum specifications. NMR magnet to include:

• 9.4 Tesla (1H @ 400 MHz) Wide Bore (WB, 89 mm) Actively Shielded (AS) Magnet. AS feature is required to minimize magnet footprint of NMR magnet
• Liquid He hold time of at least 150 days
• Magnet to be suspended on pneumatic vibration stabilization system
• Shim stack for magnet, must have at least 23 channels, and to be able to work with corresponding shim power supply w/NMR spectrometer
• Must include meters for measuring cryogen levels
• Must include liquid He transfer line

• Two channel (XY or dual full-band configuration) NMR spectometer
• Both channels must be able to generate (low power) resonant pulsed rf radiation that can reach nuclei from 1H(400MHz) to below 131Xe(<10 MHz)
• One channel must cover from 1H down to 13C and the other from 19F down to 131XE in a 9.4T field
• Spectrometer must be modular in design and expandable to a third broad band rf channel
• Must be able to apply modulated high-power rf pulses on two channels simultaneously
• Must be able to acquire NMR signals (FIDs) from both channels simultaneously
• Must be able to quantitatively compare NMR signal strengths from different experiments with different gain settings, pulse tipping angles, signal averages etc
• Must have receiver bandwidth of at least 3 MHz and configured for solids-level experiments and rf power
• All components to be able to handle high power (~1000W)
• PC or workstation for operating the spectrometer, including acquiring and pre-processing data
• Must include NMR acquisition software for spectrometer, including an object-oriented NMR pulse-programming package
• Computer to be network ready
• Delivery and installation to be included in price
