Peroksidimittauksilla, which translates to "peroxide measurements" in English, refers to the analytical techniques used to determine the concentration or presence of peroxides in various substances. Peroxides are compounds containing an oxygen-oxygen single bond. While some organic peroxides are intentionally synthesized and used as initiators or curing agents, many are undesirable byproducts of oxidation processes that can lead to degradation of materials and health hazards.

The methods for peroxide measurements vary depending on the sample matrix and the specific peroxide of interest. Common analytical techniques include titration, spectrophotometry, and chromatography. Iodometric titration is a widely used method where peroxides oxidize iodide ions to iodine, which can then be titrated with a reducing agent like sodium thiosulfate. Spectrophotometric methods often rely on reactions that produce a colored compound proportional to the peroxide concentration, allowing for colorimetric detection. Chromatographic techniques, such as high-performance liquid chromatography (HPLC) or gas chromatography (GC), can be employed to separate and quantify individual peroxides, especially in complex mixtures.

Peroxide measurements are crucial in numerous fields. In the food industry, they are used to assess the oxidative stability of fats and oils, indicating rancidity and potential spoilage. In the polymer industry, peroxide measurements help monitor the curing process of resins and the degradation of polymers due to oxidation. The pharmaceutical industry utilizes these measurements to ensure the stability and safety of drug formulations. Environmental monitoring also involves peroxide analysis to detect pollutants. The accurate determination of peroxide levels is essential for quality control, safety assessments, and understanding chemical reactions.
