Chemical Analysis |Electron paramagnetic resonance (EPR) spectrometer
Used in fields such as material research and quantum physics, electron paramagnetic resonance (EPR) spectrometry can provide structural and dynamic data on sustained chemical processes in a non-invasive manner. EPR does this by assessing the resonance frequencies of unpaired electrons found in inorganic species that contain metal ions with unpaired electrons, or organic radical species.
The essential components of an EPR spectrometer are the microwave bridge and the EPR magnet. The microwave bridge generates electromagnetic waves that are guided in the direction of a cavity or resonator where the test sample is positioned. The cavity and the sample are subjected to a magnetic field while EPR measurements are produced by the EPR magnet.
