NMR Spectrometer: 300-MHz (7.05 Tesla) WB Varian NMR System (Solids) - (Mazama)
- 300 MHz 1H frequency
- VnmrJ 3.1 software
- Three radio frequency (RF) channels
- Capable of solid-state and high-pressure experiments
Highlighted Research Applications
- Characterization of natural and soil organic matter (NOM and SOM)
- CO2 sequestration investigations via high-pressure MAS probe
- 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.
Solid-state MAS probes (Varian)
- 4.0-mm HXY probe
- 18 kHz maximum spin rate.
- 5.0-mm HXY probe
