Polarization transfer methods for quantitative analysis of flowing mixtures with benchtop 13C NMR spectroscopy [PDF]
, 2023 Benchtop NMR spectroscopy is attractive for process monitoring; however, there are still drawbacks that often hamper its use, namely, the comparatively low spectral resolution in 1H NMR, as well as the low signal intensities and problems with the ...

Benchtop In Situ Measurement of Full Adsorption Isotherms by NMR [PDF]
Journal of the American Chemical Society, 2021 Physisorption using gas or vapor probe molecules is the most common characterization technique for porous materials. The method provides textural information on the adsorbent as well as the affinity for a specific adsorbate, typically through equilibrium pressure measurements.

Benchtop NMR analysis of piperazine‐based drugs hyperpolarised by SABRE [PDF]
Magnetic Resonance in Chemistry, 2020 AbstractPiperazine‐based drugs, such as N‐benzylpiperazine (BZP), became attractive in the 2000s due to possessing effects similar to amphetamines. Herein, BZP, in addition to its pyridyl analogues, 2‐, 3‐, and 4‐pyridylmethylpiperidine (2‐PMP, 3‐PMP, and 4‐PMP respectively) was subjected to the hyperpolarisation technique Signal Amplification By ...
