This standard is proposed by the National Environmental Electronics Standardization Technical Committee (SAC/TC297). The drafting of this standard. China Inspection and Quarantine Science Research Institute, Guangdong Entry-Exit Inspection and Quarantine Bureau, Beijing Entry-Exit Inspection and Quarantine Bureau, Chongqing Entry - Exit Inspection and Quarantine Bureau. The main drafters of this standard. Wang Hongwei, Xiao Haiqing, Chen Lihua, Guo Xingzhou, Bai Hong, Fu Yanling, Tao Ziqiang, Xiao Qian, Cui Fengyun, Restricted Substances in Electrical and Electronic Products Determination of triphenyltin by gas chromatography - mass spectrometry Caution - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set forth in the relevant national regulations.1 ScopeThis standard specifies the method of gas chromatography-mass spectrometry for tributyltin and triphenyltin in electrical and electronic products. This standard applies to the determination of tributyltin and triphenyltin in electrical and electronic products.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Analysis of laboratory water specifications and test methods GB/T 6682-20083 principleThe tributyltin and triphenyltin in the sample were extracted by Soxhlet extraction with methanol as solvent. The extract was filtered and derivatized. Phase chromatography - mass spectrometry for separation and determination, external standard method quantitative.4 Reagent or materialUnless otherwise stated, use only analytical pure reagents and tertiary water in accordance with GB/T 6682-2008. 4.1 methanol. pure chromatography. 4.2 n-hexane. pure chromatography. 4.3 Sodium tetraethylborate. 4.4 anhydrous sodium acetate. 4.5 glacial acetic acid. 4.6 anhydrous sodium sulfate. 650 ℃ before burning 4h, stored in the dryer in the spare. 4.7 Tributyltin chloride Purity. ≥98%. 4.8 Triphenyltin chloride Purity. ≥98%. 4.9 2% sodium tetraethylborate solution. Weigh 0.2g tetraethylborate (4.3), accurate to 0.001g, quantitative transfer to the quantitative container, plus Water volume to 10mL. Note. sodium tetraethyl borate in a dry environment to quickly weighed, the solution is now with the current use. 4.10 acetic acid - sodium acetate solution (pH = 4.75). Weigh 1.36g sodium acetate (4.4), accurate to 0.001g, quantitative transfer to the quantitative container, Add 90mL of deionized water, with glacial acetic acid (4.5) to adjust the pH to 4.75, with water volume to 100mL, is now with the current use. 4.11 standard stock solution (1000mg/L). organic tin standard stock solution concentration to organic tin cation concentration. Priority to use evidence Standard substance (CRM) can also be prepared by weighing 0.112 g of tributyltin chloride (4.7) and 0.110 g of triphenyltin chloride ...... |
