The present application discloses systems and methods for analyzing a chemical substance containing quadrupolar nuclei to determine a measurable characteristic of the substance. The systems and methods include irradiating the substance with RF energy to stimulate NQR of certain quadrupolar nuclei within the substance, receiving and processing a signal emitted from the substance to isolate an NQR signal therefrom, analyzing the NQR signal to obtain a measure of the characteristic of the substance, and providing an output indicative of the measure for analytical purposes.

System and method for improving the analysis of chemical substances using NQR

An explosives detection system which includes computed tomography (CT) and quadrupole resonance (QR) sensors for identifying particular explosive compounds present in passenger baggage. The CT sensor may be configured to automatically identify the presence or absence of bulk military, commercial, and sheet explosives during CT scanning of the baggage. Similarly, the QR sensor may be configured to responsively generate RDX and PETN signals during QR scanning of the passenger baggage. Using any of a variety of inspection protocols, the explosives detection system may generate an output alarm based upon data obtained from the CT and QR sensors.
