Nuclear Magnetic Resonance Facility

The NMR Facility at Southern Illinois University is a university-wide facility. It has three Varian high-field multinuclear spectrometers, an Inova 500, a Mercury plus 400, and an Inova 300 wide-bore.

The Inova 300 is usually configured with a 5 mm AutoSwitchable 4-nucleus PFG probe tuned to ¹H, ¹⁹F, ¹³C, and ³¹P but which can be tuned to other X-nuclei. This instrument also can be configured with broadband probes for 10 mm and 16 mm sample tubes.

The Mercury plus 400 is equipped with an AutoX probe with Protune Accessory. Normally tuned to ¹H and ¹³C, the probe can be retuned to ¹⁹F and the range of ¹⁵N to ³¹P completely by computer control. This spectrometer has higher power amplifiers and higher power Performa II pulsed field gradients.

The Inova 500 is generally set up for proton NMR of biological macromolecules. It has 4 RF channels, each with a waveform generator, configured full-band/high-band/low-band/low-band, and the deuterium decoupling accessory is included. The probe usually in position is a PFG H/C/N but other probes are available for X-nuclei (10 mm) when there is a need for maximum sensitivity or resolution.

These instruments are available for use by SIUC researchers at attractive rates with discount rates available for extended data collection periods. Facility personnel are available to serve as technicians for an additional $20.00 per hour - otherwise researchers who wish to operate the instruments themselves will be fully trained by the Facility. These rates are designed with the intent that all operating expenses, other than the Director's salary, are recovered.

The Facility is located in the basement of Neckers Building on SIUC's Carbondale campus. It is usually open during normal working hours. After-hours access for qualified researchers can be arranged.
