Electron Spin Resonance (ESR/EPR) Spectroscopy

Electron Spin Resonance (ESR), also known as Electron Paramagnetic Resonance (EPR), is a technique for studying materials with unpaired electrons. ESR spectroscopy helps analyze radicals, transition metal complexes, and defects in solids. To ensure precision, ESR spectroscopy requires reference standards for instrument calibration. At CymitQuimica, we provide ESR/EPR Spectroscopy Standards for various research applications in chemistry, physics, and material sciences.
