Abstract:

Although the portable NMR spectrometers usually have lower signal-to-noise (SNR) and resolution compared to superconducting nuclear magnetic resonance (NMR) spectrometers, they show great advantages in more practical applications, such as fast on-site testing. In recent years, the rapid advances in hardware and experimental methods improved portable NMR spectrometers considerably, in terms of both robustness and analysis ability. This paper introduces recent progresses of portable NMR spectrometers in several aspects: hardware and software developments, high-resolution experimental methods, applications, and prospective on their future development.

Key words: portable NMR, miniaturized permanent magnet, high-sensitivity probe, integrated spectrometer, high resolution
