To summarize, we have demonstrated that it is possible to hyperpolarize the 13 C nuclei of isotopically labelled succinate using a compact, low-cost apparatus which exploits para-enriched hydrogen gas, a cheap and readily available substance. The achieved level of ∼ 6% 13 C-polarization could readily be increased to ∼ 18% by using pure para-H 2 gas. This polarization level is competitive with dissolution-DNP procedures but is achieved far more rapidly and with much less cost. This suggests the feasibility of this method for producing hyperpolarized 13 C- succinate for metabolic imaging applications. Further improvements in the yield and throughput are likely to be possible, for example by operation at higher pressure and temperature .
