300 MHz NMR Mazama (Solids)

Highlighted Research Applications

  • Characterization of natural and soil organic matter (NOM and SOM)
  • CO2 sequestration investigations via high-pressure MAS
  • Amorphous material characterization (e.g. glass).

Researchers may operate the system independently and can be trained to manage fully self-directed operations. Collaborative work with staff scientists is encouraged.
