A mobile and low-cost apparatus for dynamic nuclear polarization (DNP) hyperpolarization based on a Halbach magnet is presented and its performance is demonstrated at room temperature and with three different radical species dissolved in a glycerol-water mixture. DNP enhancement factors for a triarylmethyl-based radical, TEMPOL and a polyelectrolyte spin-labeled with nitroxide radicals are measured as a function of the microwave power, and the extrapolated maximum enhancement factors are compared. The spin-labeled polyelectrolyte shows the best DNP efficiency and1H DNP enhancement factors up to −50 were observed and a maximum enhancement factor of −80 was projected. The results demonstrate that with the new mobile apparatus reliable DNP experiments can be performed with reasonably high1H-DNP enhancements.
