3D-printed system optimizing dissolution of hyperpolarized gaseous species for micro-sized NMR

Abstract

Dissolution of hyperpolarized species in liquids of interest for NMR is often hampered by the presence of bubbles that degrade the field homogeneity. Here a device composed of a bubble pump and a miniaturized NMR cell both fitted inside the narrow bore of an NMR magnet is built by 3D printing. ¹²⁹Xe NMR experiments performed with hyperpolarized xenon reveal high and homogeneous dissolution of the gas in water.
