In nuclear magnetic resonance (NMR) the demand for compact, low-cost instruments that can substitute expensive superconducting magnets is growing. Although compact NMR devices based on permanent magnets that can resolve H chemical shift differences are commercially available, the magnetic field strength of these devices is limited, which sets boundaries to the signal intensity and quality. Hyperpolarization techniques to boost the NMR signal beyond its thermally given polarization are well known and applied on superconducting magnets. Thus, implementing these methods on compact NMR instruments will be the next step of development to gain an increased signal quality and widen the range of applications for those magnets.
