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,

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.

NMR at low magnetic fields

Chemical Physics Letters, 2009
Abstract NMR provides outstanding information in chemistry and in medicine. But the equipment is expensive as high-field magnets are employed. Low-field NMR works with inexpensive permanent magnets. Until recently these did not provide fields sufficiently homogeneous for spectroscopy and were mostly used for relaxation measurements.

Gated cardiac imaging using low-field NMR

Physics in Medicine and Biology, 1986
A system for the ECG gating of NMR images is described. It is based on the Aberdeen Mark 1 0.04 T imager and a 280 microprocessor to control data acquisition. The collection of images is discussed including: saturation recovery images; inversion recovery images and phase-encoded images.

Low Field NMR Water Cut Metering

Canadian International Petroleum Conference, 2002
Abstract We have developed a new on line water cut meter using low field Nuclear Magnetic Resonance (NMR) technology. This instrument is designed for use on heavy oil systems where conventional instruments experience difficulties.

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.
