Nuclear Magnetic Resonance (NMR) Mouse
The ISAAC mobile lab is equipped with a custom made (Magritek LTD) portable unilateral NMR sensor with a permanent magnet geometry that generates a flat sensitive volume parallel to the scanner surface, at a field strength of 0.5 T. The system is contactless and can measure, over any surface area, non-invasively, proton density (e.g. moisture content), T2 NMR relaxation times as short as 15 ms, T1 NMR relaxation times, self-diffusion coefficient of liquids, and correlations between these parameters. The scanner produces one-dimensional profiles of any of these parameters in the sample structure in situ, as it is secured to a lift capable of step increments as small as 30 mm.
Two NMR Mouse units are available, one with a slice height at 5 mm and a newer one at a slice height of 2mm.
