一个光谱仪结合高转变温度直流超导量子干涉装置（SQUID）是用来获得核磁共振信号的质子在矿物油在室温下在外地高达3 mT。SQUID磁强计在77 K和室温下的样品之间的空间间隔小于1 mm。在2 mT下，信号很容易在单次扫描中分辨。在2 mT下获得由浸在矿物油中的有机玻璃或玻璃片组成的样品的二维图像。
A spectrometer incorporating a high transition temperature dc superconducting quantum interference device (SQUID) is used to obtain nuclear magnetic resonance signals from protons in mineral oil at room temperature in fields up to 3 mT. The spatial separation between the SQUID magnetometer at 77 K and the sample at room temperature is less than 1 mm. At 2 mT, the signal is easily resolved in a single scan. Two-dimensional images of samples consisting of pieces of lucite or glass immersed in mineral oil are obtained at 2 mT.
