Sample preparation of 129Xe for dDNP with different glassing solvents, radical choice and concentrations affects the electron properties as well as the overall achieved 129Xe polarization. A short T1e and/or poor mixing is improved by ad hoc solutions that results in competitive polarization values in solid state measurements.
The sample preparation of 129Xe for DNP showed an improved incorporation of the gas atoms in the solvent when using ultrasonication. Applying microwave frequency modulation during the irradiation reached a higher 129Xe polarization. Extracted Xe was measured in a 1T NMR benchtop spectrometer to be 18s.
