NMR Spectrometer: 600 MHz NB Varian Inova

The Varian Unity 600-MHz nuclear magnetic resonance (NMR) spectrometer is a narrow-bore system equipped with a Varian Unity console. EMSL researchers use this system to perform solution-state NMR experiments primarily related to protein structure determination, and metabolomic studies are now also being conducted.

The console is equipped with three radio frequency channels and a Z-axis gradient amplifier. The solutions probes include a 5-mm HCN (Z-gradient) probe and a 5-mm HX (Z-gradient) probe. The console is controlled by a Sun Ultra 5 computer connected to the network.

Researchers may operate this system independently and are provided as much training as necessary for independent operation. Many users opt to operate this system remotely; in this case, the sample is shipped by the user to EMSL, where a facility researcher places the sample in the magnet and tunes the probe. The user can then operate the spectrometer through a secure connection over the Internet.
