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.

Hyphenated low‐field NMR techniques: combining NMR with NIR, GPC/SEC and rheometry

Magnetic Resonance in Chemistry, 2015
Hyphenated low‐field NMR techniques are promising characterization methods for online process analytics and comprehensive offline studies of soft materials. By combining different analytical methods with low‐field NMR, information on chemical and physical properties can be correlated with molecular dynamics and complementary chemical information.

Oil-Viscosity Predictions From Low-Field NMR Measurements

SPE Reservoir Evaluation & Engineering, 2005
Summary Canada contains vast reserves of heavy oil and bitumen. Viscosity determination is key to the successful recovery of this oil, and low-field nuclear magnetic resonance (NMR) shows great potential as a tool for estimating this property. An NMR viscosity correlation previously had been developed that is valid for order-of-magnitude

Evaluation of Composites Miscibility by Low Field NMR

International Journal of Polymeric Materials, 2007
Solid state nuclear magnetic resonance (NMR) is a powerful technique to analyze polymer composites. The use of proton relaxation data to evaluate the dispersity of the dispersion phase in the composite and its homogeneity are very wide. In this work PVC/silica composites were prepared using different ratios to obtain a new material to be used in ...

A low field NMR imager for clinical use

Journal of Physics E: Scientific Instruments, 1987
The essential design features of a vertical field 0.08 T, 3.4 MHz NMR proton imager are described. The machine was constructed in-house following successful clinical trials with a prototype 1.7 MHz imager. Based on a four-coil air-cored resistive electromagnet, the machine acquires single-slice 128*128 pixel images in about 4 min using an interleaved ...
