The detection standard of organic tin content is determined according to different application scenarios. For example, organotin compounds are not commercially available when used as biocides in free-associated paints. In trisubstituted organotin compounds, the tin content is required to be no more than 0.1wt%. For mixtures or articles supplied to the public, the tin content in dibutyl compounds is required not to exceed 0.1 wt%. Organotin content refers to the content of organotin compounds in a substance. Due to the toxicity and environmental pollution of organotin compounds, organotin content is strictly regulated in many fields.
The detection of organotin content requires the use of some chemical analysis methods, the more common ones include gas chromatography-mass spectrometry (GC-MS) and liquid chromatography (HPLC) etc. Detection requires collecting samples, processing and preparing them with corresponding reagents, and then identifying and measuring organotin compounds through chromatographic separation and mass spectrometry detection.
Different countries and regions have different standards for organic tin content. For example, in Europe, the limit of organic tin content is 0.1ppm, while in the United States, organic Tin content limits vary depending on the use environment and substances. In practical application, it is necessary to strictly control the content of organic tin and comply with relevant regulatory standards to ensure the safety and environmental protection of the production process.
