Boosting Dissolution Dynamic Nuclear Polarization by Cross Polarization

The efficiency of dissolution dynamic nuclear polarization can be boosted by Hartmann-Hahn cross polarization at temperatures near 1.2 K. This enables high throughput of hyperpolarized solutions with substantial gains in buildup times and polarization levels. During dissolution and transport, the C-13 nuclear spin polarization P(C-13) merely decreases from 45 to 40%.
