RMN de Paillasse à Transformée de Fourier: Le Renouveau de la RMN à Bas Champ.

Abstract : SUMMARY Whether on an academic or industrial context, the current enthusiasm for the «benchtop» compact NMR with Fourier transform (FT) illustrates new needs in spectral analysis (education, routine analysis, quality control, ...). Advantageously, this new generation of instruments is characterized by a lower purchase and operating cost compared to « conventional » instruments equipped with superconducting magnets, while offering a less-restrictive setup due to their small sizes and their low magnetic fields. This re-interest for low-field NMR has seen the emergence of a modern range of benchtop NMR spectrometers combining the advantages of FT and the use of permanent magnets (< 2 T), and whose performances have benefited from the continuous developments of the high-field NMR. Given the diversity of the current offer, a study has been launched among the various manufacturers in order to compile the main characteristics / performances / specificities of their models and offer a useful panorama to all future purchasers. In a first part, we will describe the analytical stakes, the current potentialities and the fields of application of these new instruments. In addition, a comparative synoptic table summarizing the main characteristics of the devices currently available (April 2017) on the market will be proposed. Although excluded from the comparison, the analytical and application perimeters of NMR relaxometers, other category of benchtop NMR spectrometers will be briefly discussed.
