Solid State NMR Magnets

The Oxford University Biomembrane Structure Unit currently has four magnets located in R34 at the Rutherford Appleton Laboratories, Harwell.

All magnets are wide-bore (89mm bore diameter) and have a range of probes to suit the fields. We currently have probes suitable for static (non-spinning) work and for magic-angle spinning studies. Rotor sizes vary from 2.5 - 7mm diameter. The probes are single-. double-, or triple-channeled, including a 4mm 1H19FX probe from Varian, Inc.

Experiment acquisition is supported by consoles from Chemagnetics, Varian, and Bruker. Our most recent magnet and console installation was in January 2005 when a new 500/89 shielded Magnex magnet was installed together with a Varian Infinity+ console.

Oxford Instruments 400 MHz:

The 400 MHz wide-bore Oxford Instruments magnet is supported by a 3-channel CMX Infinity spectrometer (1H 1 kW and 2 broadband 1 kW amplifiers).

Bruker 400 MHz:

Spectrospin wide-bore magnet is supported by a Bruker Avance 400 spectrometer (1H 1 kW and 2 broadband 1 kW amplifiers).

Magnex 500 MHz (Infinity+):

The 500 MHz wide-bore Magnex magnet is shielded and is supported by a 3-channel Varian Infinity+ spectrometer (1H 1 kW and 2 broadband 1 kW amplifiers).Probe base:
  • Varian 4mm HX MAS
  • Varian 4mm HFX MAS
  • Varian 6mm HXY MAS
  • Varian X Static
  • Magnex 800 MHz (Infinity+):


    The 800 MHz wide-bore Magnex magnet is unshielded and is supported by a 3-channel Varian Infinity+ spectrometer (1H 1 kW and 2 broadband 1 kW amplifiers).Probe base:
  • Varian 2.5mm HX MAS
  • Varian 3.2mm HX MAS
  • Varian 4mm HXY MAS
  • DOTY 5mm HX MAS
