Benchtop NMR for the monitoring of bioprocesses

Magnetic Resonance in Chemistry, 2019
AbstractBenchtop NMR devices are transportable, convenient, and affordable, unlike high‐field devices based on superconducting magnets. Such devices have opened numerous applications across a broad variety of scientific areas. This minireview focuses on the usefulness of benchtop nuclear magnetic resonance (NMR) for the monitoring of bioprocesses ...

Benchtop NMR spectrometers in academic teaching

TrAC Trends in Analytical Chemistry, 2016
Abstract Cost and workflow considerations can render high-field NMR spectrometers a poor match for hands-on learning in an undergraduate teaching laboratory curriculum. Recent developments in permanent magnet technology have enabled a new class of NMR instrumentation: the benchtop spectrometer. These small, affordable, low-field NMR spectrometers (40–

Frother concentration measurement with a benchtop NMR spectrometer

Minerals Engineering, 2022
In the present study, the previously developed frother concentration analysis technique based on the solid phase extraction process and the cryogen-free benchtop NMR is extended. We demonstrate that this technique can accurately quantify the concentrations of the most widely used flotation frothers such as methyl isobutyl carbinol (MIBC) and ...

Low-field and benchtop NMR

Journal of Magnetic Resonance, 2019
NMR started at low field. Important discoveries like the first observation of NMR in condensed matter, the spin echo, NMR for chemical analysis, Fourier NMR spectroscopy, 2D NMR spectroscopy and magnetic resonance imaging happened at field strengths considered low today.

Applications of quantitative NMR using benchtop NMR spectrometer.

2021
In this thesis, quantification procedures are designed and tested on two case studies to inves- tigate the application of benchtop NMR spectrometer on quantitative NMR spectroscopy (qNMR). Prior to the investigation on the benchtop NMR spectrometer, the fundamental theories of qNMR and analysis using internal and external standards are demonstrated on ...
