The Nuclear Magnetic Resonance Laboratory is equipped with state-of-the-art magnetic resonance equipment suitable for liquids and solids experiments.
Multi-nuclear capabilities, including 1H, 11B, 13C, 19F, 15N, 29Si, 31P, 119Sn and other nuclei.
Z-gradients for diffusion measurements and gradient-selected techniques.
Multidimensional techniques: 1H, correlation spectroscopy (1H-COSY), Total Correlation Spectroscopy (TOCSY), Heteronuclear Single-Quantum Correlation spectroscopy (HSQC), Heteronuclear Multiple Quantum Correlation spectroscopy (HMQC), Heteronuclear Multiple-Bond Correlation spectroscopy (HMBC), Nuclear Overhauser Effect Spectroscopy (NOESY) and Incredible Natural-Abundance Double-Quantum Transfer Experiment (INADEQUATE).

Magnet: standard bore.
1 mm CPMAS double channel (H/F-X) probe
Sample volume 0.8 ul. Max spinning speed 80 kHz.
This solid state NMR probe uses 1 mm o.d. sample rotors and provides a very high spin rate at the magic angle. It requires only sub-milligram amounts of sample for high resolution 1H solid state measurements, quantitative 1H analyses and 1H observe 2D measurements (indirect detection).
3.2 mm CPMAS double channel (H/F-X) probe
Sample volume 50 ul. Max spinning speed 22 kHz.
This solid state NMR probe uses 3.2 mm o.d. sample rotors and is a general purpose CPMAS probe balancing spinning speed and sensitivity.
ROYAL probe (RO5AT)
5mm probe with sensitivity for 31P – 15N comparable to traditional tuneable probes and sensitivity for 1H & 19F comparable to the traditional inverse probe. This provides optimum sensitivity for all nuclei.
Automatic tuning capabilities.

Magnet: standard bore.
Tuneable probe (TH5AT)
Standard 5 mm tuneable probe whit sensitivity optimized to lower sensitivity nuclei (31P – 15N).
Sensitivity for high frequency nuclei (1H & 19F) is also good.
Automatic tuning capabilities to change nucleus in consecutive measurements.
Pulsed field gradient capability.
Inverse probe (H5XAT)
5 mm probe with inverse geometry. Sensitivity optimized for 1H observation. Recommended for 1H measurements including inverse experiments (1H observed 2D experiments).
