Broadline NMR spectra Up: Porous Media Characterisation

There are a number of techniques based on Nuclear Magnetic Resonance that can be used to study porous materials, both directly and indirectly -

All of these techniques are available at the Kent University
Centre for Materials Research :


These techniques are listed in approximately length-scale order to which they are best suited :
NMR spectral techniques are sensitive to structure at atomic length scales, Cryoporometry works well for 1nm to 1um, bounded liquid fraction from 0.1um to 10um, and direct 3D imaging from about 100um; the upper length scales used to be limited by what would fit in the magnet and sample coil - with mobile NMR there is now no upper limit to the length scale that can be studied.
