Online Coupling of 80 MHz Benchtop 2D-COSY NMR to HPLC. [PDF]

Macromol Rapid Commun
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.

What is the best spectroscopic method for simultaneous analysis of organic acids and (poly)saccharides in biological matrices: Example of Aloe vera extracts?

Talanta Open, 2023
Several species of (poly)saccharides and organic acids can be found often simultaneously in various biological matrices, e.g., fruits, plant materials, and biological fluids. The analysis of such matrices sometimes represents a challenging task.

Multi-scale benchtop 1H NMR spectroscopy for milk analysis [PDF]

LWT, 2021
Abstract Benchtop NMR systems offers various advantages such as being easy to use, not requiring constant maintenance and being available at affordable prices. In this study, multiple aspects of benchtop NMR spectroscopy were explored to analyze milk in an industrial context, either regarding the quality of production or regarding the differentiation

Functionalized Controlled Porous Glasses for Producing Radical-Free Hyperpolarized Liquids by Overhauser DNP

Molecules, 2022
Overhauser dynamic nuclear polarization (ODNP) can be used as a tool for NMR signal enhancement and happens on very short time scales. Therefore, ODNP is well suited for the measurement of fast-flowing samples, even in compact magnets, which is ...
