Varian INOVA 750

This is a research-grade 750 MHz NMR instrument. In addition to the tremendous dispersion and sensitivity which this instrument provides, it is outfitted with accessories to perform virtually every known NMR experiment. Some accessories available are: 1H/13C/15N probe with cryogenically cooled rf coils (to increase signal-to-noise levels by almost five-fold), four broadband rf channels, a broadband lock channel, 5 and 10 mm probes for observation of every nucleus in the periodic table, indirect detection probes, pulsed field gradients, variable temperature, triple resonance accessory with probes to simultaneously irradiate 1H/13C/X (where X is any nucleus with a resonance frequency between those of 15N and 19F, and waveform generators for selective excitation. The instrument is also equipped with solid-state NMR accessories including: an ultra-high speed magic angle spinning (MAS) probe, 5 MHz digitizer and high power amplifiers for 1H decoupling and wideline NMR. Once the field strength of this instrument is reached, most new capabilities are provided by advancements in computers, software and radiofrequency electronics. A new console was recently purchased for this instrument (delivery is scheduled for the spring of 2011). This console replacement will maintain this instrument with state-of-the-art capabilities. The upgraded console will at minimum duplicate existing capabilities (but with better performance specifications), will provide improved solid state NMR performance, and will provide five rf channels for more flexible performance in multiple resonance experiments.

Samples for this instrument must be submitted with a lower field NMR; spectrum to verify the suitability of the sample. Users who have a regular need for this instrument's capabilities in their research and who have demonstrated proficiency on the INOVA 400 can be checked out to use this instrument.

The nature and variety of experiments which are performed on this instrument require that time be scheduled at least one (1) week in advance. Contact Dr. Venkat Dudipala by NOON on Thursdays to request instrument time for the following week.
