Benchtop Online Micro-ESR from Active Spectrum

Active Spectrum’s on-line Micro-ESR sensor is the world’s first industrial process monitoring instrument that offers embedded, non-destructive measurement of free radicals and transition metals.

Active Spectrum's on-line Micro-ESR sensor uses the principle of Electron Spin Resonance (ESR/EPR) spectroscopy to determine the concentration and composition of free radicals in any solid or fluid sample. Magnetic resonance spectroscopy is not affected by sample opacity or density. This makes Micro-ESR ideal for analyzing emulsions, opaque liquids and non-metallic solids that cannot be analyzed in other ways.
