Scheme 1.

HET-PHIP polarizer apparatus and low-field NMR setup. This setup consists of three major components (outlined by dashed lines): parahydrogen generator, propane hyperpolarizer, and the 0.0475 T NMR spectrometer/pulse-programmable automated gas manifold controlled by Kea2 NMR spectrometer with a pressurized phantom (~17.5 mL).
