Fig. 1. Schematic representation of the PHIP-SAH workflow; (A) full workup that includes: pH2 bubbling (20 s), MINERVA polarization transfer (10 s), base addition (1 s), acetone evaporation (8 s), buffer addition (1 s) and filtration (3 s); (B) decarboxylation process to obtain PHIP-H13CO3−/PHIP-13CO2 (reaction takes 45 s), and pH measurement at 7 T.
