Low-field 14N nuclear magnetic resonance for detection of dangerous liquids

The T1 and T2 relaxation times of some nitrogen-containing liquids were measured by 14N pulse nuclear magnetic resonance (NMR) in the magnetic field of 0.575 T. The liquids measured in this paper were energetic and toxic substances as well as some electrolytes. A method of the fast discrimination of...

Summary:The T1 and T2 relaxation times of some nitrogen-containing liquids were measured by 14N pulse nuclear magnetic resonance (NMR) in the magnetic field of 0.575 T. The liquids measured in this paper were energetic and toxic substances as well as some electrolytes. A method of the fast discrimination of dangerous liquids by the low field 14N NMR relaxation parameters was proposed. It is shown that flammable and toxic nitrogen-based liquids have small values of T1 and T2, therefore these liquids may be discriminated from the group of less dangerous liquids.
