Desktop fast-field cycling nuclear magnetic resonance relaxometer
Solid State Nuclear Magnetic Resonance, 2010In this paper a new type of Fast Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) relaxometer with low power consumption (200W) and cycle to cycle field stability better than 10(-4) is described. The new high-permeability magnet was designed to allow for good magnetic field homogeneity and allows for the sample rotation around an axis perpendicular

Fast-field-cycling NMR: Applications and instrumentation
Applied Magnetic Resonance, 2001Magnetic field cycling in nuclear magnetic resonance (NMR) experiments has been used since the early days of NMR. Originally such time-dependent magnetic field experiments were motivated to study cross relaxation, spin system thermodynamics and indirect detection of quadrupolar resonance.

Fast field-cycling nuclear magnetic resonance spectrometer
Review of Scientific Instruments, 1996We describe here the design and construction of a modern, state-of-the-art nuclear magnetic resonance (NMR) field-cycling instrument. Fourier transform NMR spectra of both liquid and solid samples can be measured, and spin-lattice relaxation times (T1Z) investigated over a broad range of magnetic field strengths ranging from 0 to 2 T. The instrument is

A fast field-cycling NMR/NQR spectrometer
Measurement Science and Technology, 1993The authors describe a fast field-cycling NMR/NQR spectrometer with a switching time of only 0.7 ms between zero field and maximum field (1 T) which uses a novel air-cored magnet design in which the magnet is cut out of a solid copper tube by means of electric spark erosion.

TECHNICAL ASPECTS OF FAST FIELD CYCLING
2005Publisher Summary Since the earliest days of Nuclear Magnetic Resonance (NMR), it has been clear that relaxation mechanisms were to play an important role in all its applications. The advent of the Fast Field Cycling (FFC) instruments has opened a number of important application areas (molecular dynamics of liquid crystals, paramagnetic contrast MRI ...

Applications of fast field cycling NMR relaxometry
2021Fast field cycling (FFC) NMR relaxometry is emerging as a powerful tool to investigate physical chemistry properties of many systems in a number of different scientific fields. As an example, it is used to investigate environmental issues such as soil erosion, water, and nutrient dynamics in environmentally relevant porous systems, to discriminate ...

NMR Fast Field Cycling Relaxometry of Unsaturated Soils
Applied Magnetic Resonance, 2014The bioavailability of water for plant nutrition in natural soils is controlled by the pore system structure and the interaction of water with the pore walls at variable degrees of saturation. For the characterization of these processes T 1 relaxometry is particularly suitable because it is not influenced by internal gradients and the ...
