Low-field NMR has received increasing attention in the recent years as several new approaches were published. As previous polarizers had no detection ability at B0 = 1.8 mT, we developed an apparatus specifically for the fields required by SABRE and PASADENA (B0 = 1 6 mT), suitable for RF calibration and the direct detection of NMR signal. PASADENA and SABRE are unique liquid-state hyperpolarization techniques which have achieved 13C NMR signal enhancement of several orders of magnitude.
