Welcome to Electron Paramagnetic Resonance (EPR)

Electron paramagnetic resonance (EPR) is the only technique that can qualify and quantify the presence of paramagnetic species (free radicals, transition metal ions, defects). EPR is a versatile, non-destructive analytical technique that can detect unpaired electrons in solids, liquids, gases, cell suspensions, and in vivo. EPR applications span across a wide range of areas from quality control to molecular research in fields such as material research, structural biology and quantum physics
