Schematic of the PHIP hyperpolarizer. The system consists
of the
following key elements: (a) a device frame, (b) NMR spectrometer and
RF amplifier(s), (c) thermoelectric cooled (TEC) manifold, (d) catalyst/precursor
containing bottle, (e) PHIP probe, (f) B0 magnet, (g) B0 magnet/RF probe cooling
fans, (h) interface to HyperBridge, (i) B0 magnet power supply unit (PSU), (j) controller unit, (k) solenoid
valves, (l) para-H2 tank, (m) propellant
inert gas tank, (n) power distribution unit, and (o) step-down pressure
regulator. The overall hyperpolarizer dimensions are ∼68 in.
(height) by ∼21 in. (depth) by 33 in. (width). See additional
details in the text and Supporting Information.
