Polarisation via endogenous radicals can also be carried out, please contact us for further details

Unique dual-core (two fields) magnet in the group of Dr. Walter Köckenberger to combine low-temperature DNP with liquid-state NMR and additional provisions for dissolution and solid-state DNP. Please contact Dr. Walter Köckenberger for further details.

The Facility can provide support to design the project regarding feasibility and effectiveness, sample preparation, running and designing experiments, and data analysis. For access, please see the protocols here.
