1 Scope

This standard specifies the plastic and its products in 12 kinds of phthalate plasticizers gas chromatography - mass spectrometry method. This standard applies to 12 kinds of plastic products and the determination of phthalate plasticizers. Phthalate plasticizers sub Substructure is. R1-CO2-C6H4-CO2-R2.12 plasticizers English name, CAS number, and the formula given in Appendix A. Principle 2 Sample using ethyl acetate as the extraction solvent, the extraction, after extraction fluid volume by gas chromatography - mass spectrometry determination, internal standard method Quantified.
