Differentiation of fentanyl analogues by low-field NMR spectroscopy
Analytica Chimica Acta, 2019 Forensic laboratories commonly receive new psychoactive substances such as fentanyl analogues and other synthetic opioids that are difficult to identify. Slight changes to chemical structures, e.g. shifting the position of functional groups such as methyl groups or halogens on the aromatic ring, may not be distinguished using traditional methods.

Low‐field
Magnetic Resonance in Chemistry, 2019 AbstractOil is a prominent, but multifaceted material class with a wide variety of applications. Technical oils, crude oils as well as edibles are main subclasses. In this review, the question is addressed how low‐field NMR can contribute in oil characterization as an analytical tool, mainly with respect to quality control.
