Miniaturized NMR-MOUSE with a High Magnetic Field Gradient (Mini-MOUSE)

Mobile nuclear magnetic resonance sensors still suffer from relatively high weight and large dimensions, although they are already considerably smaller than superconducting high-field magnets. Application of such sensors for an accurate analysis of rigid materials and thin layers is limited by the echo time of the radiofrequency (rf) coil and the spatial resolution of the …

Shaping the Sensitive Volume of a Single-Sided NMR-Sensor to Profile Cylindrical Samples with High Resolution

This work reports the construction of a single-sided magnet generating a sensitive volume with adjustable curvature. It is useful to profile cylindrical samples with high depth resolution. The sensor geometry is based on the Profile NMR-MOUSE, which generates a parabolic field profile with a quadratic coefficient that decreases with the distance from the magnet surface. …

Stacked planar micro coils for single-sided NMR applications

This paper describes planar micro structured coils fabricated in a novel multilayer assembly for single-sided NMR experiments. By arranging the coil’s turns in both lateral and vertical directions, all relevant coil parameters can be tailored to a specific application. To this end, we implemented an optimization algorithm based on simulations applying finite element methods (FEMs), which maximizes …

Ex Situ NMR in Highly Homogeneous Fields: 1H Spectroscopy

Portable single-sided nuclear magnetic resonance (NMR) magnets used for nondestructive studies of large samples are believed to generate inherently inhomogeneous magnetic fields. We demonstrated experimentally that the field of an open magnet can be shimmed to high homogeneity in a large volume external to the sensor. This technique allowed us to measure localized high-resolution proton …
