溶解的超极化物质在液体中的利益核磁共振往往受到阻碍的存在下，降低了场的均匀性的气泡。在这里，一个由气泡泵和微型NMR单元组成的设备都安装在NMR磁体的窄孔内，通过3D打印构建。用超极化氙进行的NMR-129实验揭示了气体在水中的高度和均匀的溶解。
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. Xe-129 NMR experiments performed with hyperpolarized xenon reveal high and homogeneous dissolution of the gas in water.
