To increase the SNR in earth's magnetic field NMR the macroscopic spin order of parahydrogen can be used to produce hyperpolarization. Therefore after an unsaturated substrate is hydrogenated with parahydrogen field cycling has to be applied. Here, we show that a preparation field in the regime of mT switched on for several seconds enables the transfer of PHIP-generated hyperpolarization from parahydrogen to 19 F and that this process is field dependent. For the measurement a self built coil based earth field spectrometer was used.
