NMR Spectrometer: 500 MHz NB CMX for Liquids (and solids)
Quick Specs
- 500-MHz frequency
- Capable of solid-state NMR and solution-state spectroscopy
The Varian Infinity CMX 500-MHz nuclear magnetic resonance (NMR) spectrometer is a narrow-bore system equipped with a Varian Infinity CMX console. This system is capable of performing solid-state NMR experiments and solution-state spectroscopy. EMSL researchers use the solid state for a variety of applications, including multinuclear structural studies of catalysts and new materials. The solution-state capabilities are primarily used for routine liquids NMR of organic synthesis samples, but are also used for multinuclear NMR studies.
The console is equipped with three radio frequency channels and a single gradient amplifier. The solid-state probes include a 5-mm HX MAS probe (12-KHz spinning) and a 6-mm HX MAS probe (9-KHz spinning). The solution-state probes are comprised of a 5-mm dual band (HX) probe with a Z-axis gradient, a 5-mm HCN indirect probe with a Z-axis gradient, and a 10-mm HX probe (extended tuning range on the X channel down to 21.2 MHz). 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.
