Hyperpolarizing Gases via Dynamic Nuclear Polarization and Sublimation

A. Comment et al., Hyperpolarizing Gases via Dynamic Nuclear Polarization and Sublimation, Phys. Rev. Lett., 2010, 105(1), 018104-018107.


A high throughput method was designed to produce hyperpolarized gases by combining low temperature dynamic nuclear polarization with a sublimation procedure. It is illustrated by applications to 129Xe nuclear magnetic resonance in xenon gas, leading to a signal enhancement of 3 to 4 orders of magnitude compared to the room-temperature thermal equilibrium signal at 7.05 T.
