Jahnig, F., G. Kwiatkowski, and M. Ernst, Conceptual and instrumental progress in dissolution DNP. J Magn Reson, 2016. 264: p. 22-9.
We discuss conceptual and instrumental progress in dissolution DNP since its introduction in 2003. In our view there are three critical steps in the dissolution DNP process: (i) The achievable polarization level in a sample. (ii) The time required to build up the polarization. (iii) The transfer of the sample to the measurement system with minimum loss of polarization. In this review we describe in detail these steps and the different methodological and instrumental implementations, which have been proposed to optimize them.
