PS: It is primarily used for auxiliary testing and preliminary screening. Its measurement results can serve as corroborative data for judgment, but cannot be used as the sole or final basis for decision-making.

Product Details
The easily oxidizable colorimetric method determines the consumption of oxidants (indirect method) or the color development of oxidation products (direct method), and compares the quantitative content with standard samples.
Application scenarios
1. Safety of drugs and medical devices
Purified water testing: The pharmacopoeia stipulates the use of potassium permanganate titration/colorimetric method to control easily oxidizable substances to 0.3mg/L (calculated as O ?).
Dissolved substances in packaging materials: detect reducing impurities such as infusion bags to ensure biocompatibility.
2. Food quality monitoring
Food oil peroxide value: The colorimetric method is used to determine the peroxide generated by oxidation, reflecting the degree of oil rancidity.
Preservative residue: such as sulfite, quantified through fading reaction.
3. Environmental monitoring
Reductive pollutants in water bodies: detect sulfides, phenols, etc. to avoid hypoxia in water bodies.
Atmospheric nitrogen oxides: Saltzman method uses naphthylethylenediamine hydrochloride for color development and determination of NO ? concentration.
4. Industrial process control
Purity of chemical products: Monitor the content of reducing impurities (such as aldehydes).
Metal corrosion assessment: Analyze the corrosion products of equipment through Fe 2 ? colorimetric analysis in solution.
5. Biological activity testing
Enzyme activity analysis: For example, xanthine oxidase catalyzes the production of H2O2, and indirectly determines enzyme activity through color reaction.
