Detection of Explosive Precursors Using Low-Field Magnetic Resonance Imaging

The method of nuclear magnetic resonance (NMR) is widely used for studying the liquid and solid compounds. NMR in low fields is one of the promising methods for the detection of liquid explosives and hazardous compounds. The attractiveness of low magnetic fields for solving this problem is in the low cost of the devices themselves and of their operation, and the relatively low-energy inputs for the maintenance of the magnetic field. In this work, the prospects of the application of a magnetic resonance imaging system with the low magnetic field induction for the operative differentiation of the type of the liquid were discussed. On the basis of the above study, it is possible to state that the methodology of the detection of liquid explosive and hazardous compounds using NMR in low and ultra-low fields can be elaborated and successfully introduced for providing security in crowded places.
