FAST FIELD-CYCLING NMR RELAXOMETRY: A MULTIPLE TIME-SCALE & TIME-DOMAIN TECHNIQUE

Since its origins, the fast field-cycling (FFC) NMR technique has been successfully used as key analytical tool at both scientific and industrial environments [1]. A continuous improvement of the associated hardware and data interpretation, in addition to a tested consistency with other experimental techniques, favored the adoption and extension of the technique for new applications (see figure in attached abstract).

Food analytics [2], biomedical [3] and oil & gas industry [4], are among those applications where the FFC NMR relaxometry is showing an increasing impact.

In this talk we will briefly address the main advantages of the field-cycling method compared to other time-domain NMR alternatives, and we will show its potentiality through selected exemplary cases.
