NMR Dynamic Nuclear Polarization
The NMR Centre has a state of the art dynamic nuclear polarization (DNP) NMR instrument, composed of a 600 MHz wide-bore NMR magnet and a 395 GHz gyrotron. By irradiating the sample with microwaves from the gyrotron, signal enhancements of up to 80 times can be seen. The remarkable sensitivity of the DNP allows for NMR experiments not capable on conventional NMR instruments.
The DNP probe is a triple-resonance (1H/13C/15N) 3.2 mm magic-angle spinning probe. The probe is connected to a low-temperature cooling unit, which allows for sample temperatures down to 100 K by cooling both the MAS and sample temperature gas. The spectrometer is controlled via an AVANCE III console.
The DNP system at the NMR Centre is available for use by both academic and industrial/governmental users. Please contact Dr. Sameer Al-Abdul-Wahid for more information.
