Geomagnetic NMR

Lawrence Berkeley National Laboratory researchers have shown that they can carry out nuclear magnetic resonance (NMR) spectroscopy using a magnetic field not much stronger than the Earth's magnetic field. They used the technique to analyze a mixture of hydrocarbons and water using a high-sensitivity magnetometer. The technique could lead to in situ analysis of fluid mixtures without the need to take samples back to a laboratory. The work was conducted by Alexander Pines team alongside Dmitry Budker at the University of California, Berkeley, and researchers at the National Institute of Standards and Technology.
