Bruker 300MHz SWB MRI/Diffusion Spectrometer

Instrument types

The newly ordered Bruker 300MHz Super-Wide Bore MRI/Diffusion Spectrometer has multiple capabilities.

Magnetic resonance imaging (MRI): MRI is an imaging technique used to produce high quality images of objects such as human bodies, small animals and materials. The images reflect the spatial distribution of NMR signals for the nucleus of interest over a space. As a upgrade to MRI, Rheo-NMR, a combination of NMR and Rheology, measures the rheological properties of materials at the microscopic molecular levels.

Diffusion measurement (Diff): NMR spectroscopy allows measurement of the coefficient of self-diffusion (Ds) which is defined as the translational diffusion coefficient, in the range of 10⁻8 m2/s to 10⁻13 m2/s in both solids and solutions using gradient pulses.

Solid-state NMR (SSNMR): The instrument is capable of performing routine solid-state NMR experiments.
