X-Band Micro-ESR Spectrometer (Benchtop X-Band / Active Spectrum)

The Benchtop Micro electron spin resonance (Micro-ESR) spectrometer is portable X- band spectrometer used to measure the concentration and composition of free radicals present in a sample in tube mode via magnetic resonance spectrum. The ESR spectrum gives information about the structure and dynamics of atoms and molecules through different spectrum features like the frequency of the lines (g-factor), the number of lines and spacing between them, the width, shape & intensity of the lines. The samples can be liquid, solid, emulsions, gas, or combination of phases. ESR can be used to determine the concentration and composition of free radicals, asphaltene and vanadium in crude oil, reactive oxygen and nitrogen species, spin labeling, spin trapping (BMPO, DMPO, PBN, TEMPOL, PTIO, etc.), kinetics analysis, transitions metals, rare earths, and lanthanides with unpaired electrons and their complexes. Specification: Frequency: 9.6 to 9.8 GHz Resonator: Cylindrical Dielectric Sample Tube Diameter: Up to 5.8 mm Sweep Range: Over 300 Gauss, centered at g=2
