Nuclear magnetic resonance (NMR) is a technique used for many years by chemists for elucidation of molecular structure. Technological progress over the years has enabled this technique, making it easier to use. Thus, the LF-NMR (low-field NMR) was introduced as side technique, characterized by low management costs and shorter analysis time than its main counterpart. The application of ¹H LF-NMR for the quantification of ethyl alcohol in different alcoholic matrices is herein described, comparing results obtained with this technique with those determined by a reference gascromatographic method.
