Detection Limits of Blood Metabolites at Physiological Concentrations Using Benchtop $$ {}^1 $$ H NMR. [PDF]
NMR BiomedWe demonstrate rapid, sensitive detection of key blood metabolites using an 80 MHz low‐field NMR spectrometer, benchmarking signal‐to‐noise ratios and acquisition efficiency across experimental designs. Millimolar metabolites such as glucose and lactate are reliably detected and quantified within seconds, while simulation‐assisted spectral fitting ...

Gradient-based pulse sequences for benchtop NMR spectroscopy
Journal of Magnetic Resonance, 2020 Benchtop NMR spectroscopy has been on the rise for the last decade, by bringing high-resolution NMR in environments that are not easily compatible with high-field NMR. Benchtop spectrometers are accessible, low cost and show an impressive performance in terms of sensitivity with respect to the relatively low associated magnetic field (40-100 MHz ...
