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.

Perspectives in process analytics using low field NMR

Journal of Magnetic Resonance, 2021
Low field NMR is a powerful analytical tool which creates an enormous added value in process analytics. Based on specific applications in process analytics and perspectives for low field NMR in form of spectroscopy, relaxation, diffusion, and imaging in quality control, diverse applications and technical realizations like spectrometers, time domain NMR,

A resistive Q-switch for low-field NMR systems

Journal of Magnetic Resonance, 2018
An NMR Q-switch was designed and constructed specifically for use with low-field NMR apparatus. This featured a comparatively simple resistive damping design. It served to reduce the r.f. probe ring-down time, and hence reduced the signal acquisition delay from 25 ms to 9 ms, on an Earth's magnetic field NMR system.

Optical Atomic Magnetometry for Ultra-Low-Field NMR Detection

, 2013
Abstract This chapter deals with detection of nuclear magnetic resonance (NMR) signals in the ultra-low-field (ULF) regime, by means of optical atomic magnetometers (OAMs). A general introduction is provided about specific NMR features occurring when nuclei precess in microtesla fields, or weaker.

NMR at very low fields

Magnetic Resonance Imaging, 2010
Although nuclear magnetic resonance in low fields around or below the Earth's magnetic field is almost as old as nuclear magnetic resonance itself, the recent years have experienced a revival of this technique that is opposed to the common trend towards higher and higher fields.

Low field NMR measurements in3He-A

Physica B: Condensed Matter, 1994
Abstract We are making simultaneous measurements of the longitudinal and transverse resonances in fields of the order of 30 gauss in a parallel plate geometry, defined by mylar films 100 μm apart, so that l is well oriented perpendicular to the static magnetic field.
