A method and apparatus are provided for treating hydrated material in a fluid that contains water in which a stable nitroxide is attached to the hydrated material. A dynamic nuclear polarization process (DNP) is conducted on the hydrated material whereby to hyperpolarize the water. A polarization cell contains the hydrated material to obtain hyperpolarized water free from the nitroxide. The dynamic nuclear polarization process is conducted using components comprising a tunable, solid state high power X-band driver and an X-band resonator for microwave transmission to the hydrated material. The components can also include a radio-frequency nuclear magnetic resonance probe, a permanent magnet formed to receive the hydrated material, a portable nuclear magnetic resonance spectrometer, and an electron spin resonance detector. The components can be sized to be portable, and include electrical input and output and a lap-size hard-case with access to the electrical input and output.
