400 MHz NMR Karloff (Solids)
Research Applications
- Characterization of quadrupolar nuclei for inorganic and biological materials and natural sediments
- Cryogenic NMR capabilities for 2H dynamics or wideline NMR of nuclei in dilute environments
- Characterization of terrestrial carbon in plant materials and soils.
Researchers may operate the system independently on site or remotely. Most operations are standard, but users are strongly suggested to collaborate with EMSL scientists for cryogenic operations.
NOTE: this spectrometer has limited access. Contact the instrument custodian for more details.
