Claim:
1. A system for detecting at least one compound in a material under test comprising: a Nuclear Quadrupole Resonance frequency generator configured to generate an Nuclear Quadrupole Resonance frequency (f a microwave frequency generator to generate a microwave frequency (f a radio frequency input probe for to propagate the Nuclear Quadrupole Resonance frequency to the material under test; a radio frequency output probe adapted to detect returned radio frequency signals which are returned from the material under test; a waveguide for receiving the returned radio frequency signals which are returned from the material under test; wherein the radio frequency input probe is near a first end of the waveguide and the radio frequency output probe is near a second end of the waveguide; wherein the material under test is located in the waveguide and located between the radio frequency input probe and the radio frequency output probe; and a detector adapted to detect the at least one compound based, at least in part, on whether the returned radio frequency signals which are returned from the material under test include frequencies corresponding to f
