NMR Spectrometer: 500 MHz WB Varian NMR System (solids)

Quick Specs

  • 500-MHz frequency
  • Capable of solid-state experiments
  • Coupled to microscopy capabilities

The Varian Unity Plus 500-MHz nuclear magnetic resonance (NMR) spectrometer is a wide-bore system equipped with a Varian Unity Plus console. This system is capable of performing solid-state NMR experiments, magnetic resonance imaging microscopy, and simultaneous optical and magnetic resonance imaging. EMSL researchers use the solid state for a variety of applications, including structural studies of peptides, catalysts, and very low-temperature observation of zinc in proteins and a variety of materials containing metal atoms. The imaging applications include mice; cell cultures; single cells; and a variety of non-biological samples, including plastics and rocks.

The console is equipped with three radio frequency channels and three gradient channels. The solids probes are comprised of a 5-mm HXY MAS probe, a 7-mm HX probe, a 5-mm goniometer probe, and a 5-mm probe for cryogenic static samples. A variety of imaging probes are also available, including a 40-mm probe for large objects, and several microscopy probes with perfusion capability for high-resolution work. The console is controlled by a Sun Ultra 10 computer connected to the network.

Researchers may operate this system independently and are provided as much training as necessary for independent operation.
