Comparative analysis of standard frameworks
GB/T 35492-2017 mainly stipulates the determination method of 9 kinds of organotins in latex products by gas chromatography-mass spectrometry (GC-MS). Its core contents include:
- Technical parameter requirements of gas chromatography-mass spectrometry
- Sample pretreatment steps, including extraction and derivatization process
- Preparation method of standard solution and detection limit requirements
- Result calculation and data processing specifications
Technical background and evolution analysis
Organotins are widely used in latex products because of their low toxicity and good physical and chemical properties. However, its residues may pose potential risks to the environment and human health. Therefore, it is crucial to establish accurate and sensitive detection methods.
Gas chromatography-mass spectrometry (GC-MS) combines the high separation of gas chromatography and the high sensitivity of mass spectrometry, making it an ideal choice for organotin detection. Compared with traditional spectrophotometry, GC-MS has higher sensitivity and a wider dynamic range.
