Low-Field Benchtop NMR Spectroscopy for Quantification of Aldehydic Lipid Oxidation Products in Culinary Oils during Shallow Frying Episodes [PDF]
Introduction: Toxic aldehydic lipid oxidation products (LOPs) arise from the thermo-oxidative deterioration of unsaturated fatty acids present in heated culinary oils when exposed to high-temperature frying episodes, and currently these effects represent

Online Coupling of 80 MHz Benchtop 2D-COSY NMR to HPLC. [PDF]
AbstractHPLC is coupled online for the first time to 2D‐NMR on a benchtop NMR spectrometer. The potential is demonstrated at 80 MHz with COSY (1H‐1H COrrelation SpectroscopY) for a mixture of methyl and propyl parabens, additives commonly used in cosmetics.
