Peroxsay Peroxide Assays

PEROXsay™ is a colorimetric quantitative peroxide assay that measures the oxidation of ferrous (Fe2+) ions to ferric (Fe3+) ions. Peroxides react with a sugar alcohol converting it to a peroxyl radical that subsequently starts the oxidation of ferrous ions to ferric ions. The acidic pH of the PEROXsay™ assay allows the ferric (Fe3+) ion to complex with the colorimetric reagent, resulting in a change in absorbance that is proportional to the peroxide concentration.
