300 MHz NMR Probes

Several probes are available for the 300 MHz wide-bore NMR instrument.

  • TBI 300 MHz WS1 5mm with z-gradient four-channel solution-state probe


With this probe, It is possible to observe a wide range of nuclei, ranging from high sensitivity observation of proton, carbon, phosphorous, and fluorine to allowing observation of a large number of more exotic nuclei. It is capable of performing most modern liquid phase NMR experiments including state of the art two- and three-dimensional experiments with pulsed field gradients. It is available to departmental users to solve structural problems requiring high resolution capabilities.

  • HRMAS 300 MHz W1S2 4mm solid-state probe


  • Diffusion and rheo-NMR probe

MIC 300 MHhz W1/S2 DIFF/50 diffusion probe

gradient strength = 50 (G/cm) A => maximum gradient strength = 30 T/m   at 60 A

The following inserts are available for this probe:

1H 5 mm, 1H 8 mm, 1H 10 mm, 13C-1H 5 mm, 13C-1H 8 mm

  • MRI and micro-imaging probe


Three imaging coils are available that make it possible to image a wide range of samples, such as rock samples, plants, and animals:

  • Bruker MICWB40 RES 300 1H/13C 040/005 LLTR
  • Bruker MICWB40 RES 300 1H 040/010 LTR
  • Bruker MICB40 RES 300 1H 040/025 QTR

These cover sample sizes of 5 mm, 10 mm, 25 mm that can be imaged. It is possible to insert larger samples than that into the non-imaged portion of the assembly, to accommodate animals, for example.


400 MHz NMR Probes

The 400 MHz instrument is capable of analyzing liquid samples in a variety of experiments.

Three NMR probes are available for this instrument.

  • 5 mm BBinv x,y,z gradient
  • 5 mm BBO
  • The 5.0 mm multi-nuclear observe probe with Z-gradient is used for a broad variety of experiments. It is the most frequently used probe for this instrument.

400 Probe

600 MHz NMR Probes

The 600 MHz instrument is capable of analyzing both solid and liquid samples in a variety of experiments.

  • The 5.0 mm multi-nuclear broad band observe probe is used in a broad variety of experiments including 1H observe with 19F decoupling and the observation of exotic nuclei such as 195Pt.



  • The 1.7 mm triple resonance inverse (TXI) probe (1H, 13C, 15N) is used for experiments where only small amounts of organic or biological samples are available.

BBO Probe


  • The 4.0 mm triple resonance (1H, 13C, 15N) E-free CPMAS Bio-solids probe is used for experiments on solid biological samples.

MAS probe

Anasazi Eft-60 NMR Probes

There is one probe available for the Anasazi Eft-60 that allows detection 1H and 13C. In particular the 13C detection is pretty good and quite useful. This is crucial as the natural abundance of 13C is very low (about 1.109%) that usually makes 13C-NMR quite time-consuming. In fact, many NMR spectrometers below 100 MHz proton frequency do not even offer 13C-detection.

The instrument allows operation in 1 and 2 dimensions (1D and 2D).
