In this work, we have demonstrated for the first time that an alkali vapor cell magnetometer has sufficient sensitivity to chemically resolve a heterogeneous mixture of oil and water by its relaxation and diffusion properties, both in one dimensional experiments and in two-dimensional correlation experiments, a significant step towards the use of atomic magnetometry in wider industrial applications, and a proof of-concept for a potentially powerful next generation of portable NMR sensors.
