Polarean - Model 9800 -129Xe Hyperpolarizer

The 9800 129Xe hyperpolarizer provides a routine supply of high-purity, hyperpolarized 129Xe for gas phase magnetic resonance studies. The polarizer is typically installed near the MRI/NMR suite and processes a custom mixture of unpolarized 129Xe, N2, and 4He, into one or more doses of pure hyperpolarized 129Xe that is available for magnetic resonance studies. There is no chemical change associated with hyperpolarization—only nuclear spin alignment and cryogenic extraction of pure xenon. The hyperpolarized 129Xe is then thawed and dispensed into a container or bag. Once dispensed into an appropriate container, and maintained within a modest holding magnetic field, the polarization relaxes with a T1 of 1-2 hr.
