Recent developments in dynamic nuclear polarisation now allow significant enhancements to be generated in the cryo solid state and transferred to the liquid state for detection at high resolution. We demonstrate that the Ardenkjaer–Larsen method can be extended by taking advantage of the properties of the trityl radicals used. It is possible to hyperpolarise 13 C and 15 N simultaneously in the solid state, and to maintain these hyperpolarisations through rapid dissolution into the liquid state. We demonstrate the almost simultaneous measurement of hyperpolarised 13 C and hyperpolarised 15 N NMR spectra. The prospects for further improvement of the method using contemporary technology are also discussed. Copyright © 2007 John Wiley & Sons, Ltd.
