NMR Spectrometers

In the Department of Chemistry & Biology the following centrally operated NMR spectrometers are available:

BRUKER AVANCE III 600 (Basic frequency (¹H): 600.13 MHz)

Equipment

• Probeheads:
  
  • 5mm Broadband Inverse Probehead with automatic frequency tuning (ATM)
  • 10mm ¹H/¹³C Probehead for high temperature experiments
  • 3mm QXI Quadruple Resonance Inverse-Probehead (¹H/³¹P/¹³C/¹⁵N)
• Sample Changer for 60 NMR Tubes
  

BRUKER AVANCE 400 ( Basic frequency (¹H): 400.13 MHz)

Equipment

• Probeheads :
  
  • 5mm Broadband BBFO Probehead with automatic frequency tuning (ATM)
  • 5mm QNP Probehead (¹H/¹³C/³¹P/¹⁹F)
  • 5mm Broadband Inverse Probehead
• Sample Changer for 120 NMR Tubes

The AVANCE 400 is mainly used for routine experiments with the nuclei ¹H, ¹³C, ³¹P, ¹¹B, and ¹⁹F. The 5mm BBFO probehead can be tuned and matched automatically (ATM) to these nuclei as well as to all other nuclei in the frequency range between that of ¹⁰⁹Ag and ³¹P, respectively.

In the standard mode, ¹⁹F spectra are recorded using the X channel which also allows both for ¹H decoupling and recording ¹⁹F decoupled ¹H spectra.
For special ¹⁹F experiments, the decoupler coil is tuned to ¹⁹F which offers the option to run either ¹⁹F decoupled X spectra or X decoupled ¹⁹F spectra (requires manual operation).

Routine experiments make use of the automatic sample changer (capacity 60 and 120 tubes, respectively) and the scheduled experiments are set up using Bruker IconNMR. After completion, the data are automatically transferred to the file server (see below measured data).

Current setup and history is permanently updated and displayed here.
