A rapid cycle dynamic nuclear polarization (DNP) NMR apparatus comprises (i) a cooling unit, configured to cool a sample in a capillary, (b) a DNP polarization unit configured to polarize the sample in the capillary, (c) a stripline-based NMR detector comprising a stripline for NMR analysis of the sample in the capillary, (d) a transport unit configured to guide the capillary from the DNP polarization unit to the stripline of stripline-based NMR detector; and (e) a heating unit configured to heat the sample in the capillary before analysis of the sample by the stripline-based NMR detector. Fast (1D-3D) NMR measurements with high resolution may be obtained.
