Abrégé
(EN)

A compact and integrated portable device is provided for the analysis of dispersions by low-field pulsed NMR including: an NMR probe module, a means for generating radio frequency and magnetic field gradient pulses, a signal processor, and a master controller. Also provided are methods for using the device to measure one or more characteristics of phases or particles comprising a dispersion such as surface area, solid/liquid ratio, particle size, and elemental analysis.
