1. A device for determining chemical properties of a sample, comprising:
a dielectric resonator comprised of a metallic chamber enclosure and a dielectric, both defining an opening configured to a sample to be moved through to a measurement position;
one or more permanent magnets configured to be positioned in a first position to create a condition in which the sample and resonant chamber are not in a paramagnetic resonance condition and further configured to be positioned in one or more different positions to create one or more conditions in which the sample and resonant chamber are in a paramagnetic resonance condition;
a microwave network vector analyzer configured to generate microwave radiation in the range of 1.0 GHz to 4.0 GHz and to receive and measure an amplitude and phase of reflected microwave radiation:
a magnetic-field coupling probe that is connected through one or more coaxial connectors and wires to the microwave vector analyzer and configured to couple the generated microwave radiation to the sample and resonant chamber:
a processor programmed with a set of computer-executable instructions, wherein when executed, the instructions cause the device to
measure a magnitude and phase of a reflected signal from the sample and resonant chamber;
measure a magnitude and phase reflected signal from a reference component or circuit;
determine a quality factor of the sample and resonant chamber when the sample is not in a paramagnetic resonance condition and when the sample is in one or more paramagnetic resonance conditions; and
from the measurements of the quality factor, determine at least one chemical property of the sample.
