This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Zhejiang Exit Inspection and Quarantine. The main drafters of this standard. Zhu Yu, Ding Huiying, Qin Jiang Ting. Leather chlorinated paraffin residues in detection of short-chain Gas chromatography Warning. dangerous hydrogen gas, attention to indoor air.1 ScopeThis standard specifies the leather C10 ~ C13 gas chromatography method SCCP residues. This standard applies to the determination of C10 ~ C13 leather SCCP residues. Principle 2 Samples were ultrasonic extraction, Florisil column purification, hydrogen as a carrier gas, under the action of hydrogen chloride, palladium-catalyzed after a short chain Chlorinated paraffins into linear paraffins, to detect the amount of internal standard hydrogen flame detector.
