Avance DMX500MHz SB NMR Spectrometer for Solution

The newly upgraded Bruker AVANCE500 spectrometer is a narrow bore, high resolution, NMR spectrometer that is primarily used for solution NMR spectroscopy but can also be used for solid-state NMR spectroscopy. It is a four channel spectrometer that operates at 11.7T (1H frequency of 500MHz). It is equipped with various double resonance Broadband Probeheads for both solution (5mm BBFO 1H-F/X and 10mm BBO 1H/X Double Resonance Probe) and solids (2.5mm, 4mm, and 5mm MAS 1H/X Probes), Triple-Resonance/Triple-Gradients Probe for biological solution NMR, Triple/Resonance Transmission Line Probe (under building) for solids, and 4mm hr-MAS 1H/13C z-gradient Probe for macromolecules and oriented media in solution. See the Table for more probe details.
