Methods and systems for low to ultra-low magnetic field nuclear magnetic resonance for detecting chemical nerve agents

Patent ·
OSTI ID:1892962
; ; ; ; ; ; ; ; ; ;

A nuclear magnetic resonance (NMR) system is configured to detect chemical threat material. The system comprises a magnet configured to generate a magnetic field of about 300 millitesla or less; and a probe configured to detect nuclear relaxation of at least two nuclei selected from the group consisting of 1H, 19F, 31P and 14N, and detect the spin density of nuclei selected from the group consisting of 1H, 19F, 31P and 14N, following excitation.
