The QC of DS is therefore of paramount importance to ensure their safety and to protect consumers. This represents an alarming emerging risk to public health. (14) A significant number of unscrupulous manufacturers add pharmaceutical compounds to DS to improve their effects. Considering the cost and space efficiency of these spectrometers, we anticipate their introduction in QC laboratories as well as in governmental agencies, especially in the field of fraud detection.ĭietary supplements (DS) are products between medicines and conventional foods whose consumption is rising steeply. We also showed that the quantification by the internal standard method can be done on the low-field NMR spectrometer and leads to results similar to those obtained with high-field NMR. We demonstrated that the adulterant(s) can readily be detected in ≈20 min of recording after a very simple and rapid sample preparation. In this paper, we evaluated the potential of a benchtop cryogen-free 60 MHz spectrometer for uncovering adulteration of “100% natural” sexual enhancement and weight loss dietary supplements. The recent release of benchtop cryogen-free low-field NMR spectrometers represents a technological break in the NMR field. However, due to cost constraints, NMR is rarely used in routine quality control (QC) analysis. I think I love you.Nuclear magnetic resonance (NMR) spectroscopy is a unique tool for detection, structural characterization, and quantification of compounds in complex mixtures.
