Mobile low field magnetic resonance hardware development.

Typically, NMR systems are bulky and expensive laboratory based equipment. For half a century after its scientific discovery taking NMR outside of a laboratory environment is still not a common practice due to the complexity of the underlining physical phenomena and its low sensitivity, to the myriad of technical challenges when integrating a complete system. The scarcity of compact and mobile NMR systems has prevented its proliferation into many other areas and applications. This paper describes the progress in the development of compact electronic spectrometers that we coupled with handheld sensors in order to provide complete mobile solutions. The key to this progress has been the modern advances in computing, electronics and permanent magnet technologies. Mobile NMR is now feasible as a valuable, non-invasive tool for industrial and medical applications. By leveraging the strengths of NMR, which is to probe at the molecular level and gain information about molecular structure, organisation, abundance and orientation, NMR is intrinsically suitable for non-destructive testing of a wide range of materials and their manufacturing processes. The development of complete NMR systems benefits from working across various disciplines and organisations. By embracing a collaborative approach we believe it will accelerate NMR technology to become more ubiquitous in the near future.
