Recent advances in benchtop NMR and its applications

Résumé

Benchtop NMR spectroscopy has known a major growth over the last decade, thanks to the design of permanent, compact magnets in the 1-2 T range, that provide remarkable performance in terms of resolution and sensitivity. Although resulting spectra are more limited than their high-field counterparts, the achievable structural and quantitative information can be maximized by a clever use of pulse sequences-in particular those involving gradient pulses-and by advanced data processing algorithms. In this chapter, we describe the main characteristics of benchtop NMR spectroscopy in 2020, both in terms of hardware and typical performance. We highlight the most recent methodological improvements in the field, in terms of pulse sequences, hyperpolarization and data processing, which have significantly improved the resolution and sensitivity of benchtop NMR spectrometers. Finally, we discuss major applications of benchtop NMR spectroscopy, for reaction and process monitoring, but also for quality control and profiling. The number of papers in this field in the last few years undoubtedly highlights the major role that benchtop NMR has to play for applications in areas such as food and pharmaceutical industry, flow chemistry, and profiling of complex samples.
