Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. 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, People's Republic of China Entry-Exit Inspection and Taizhou Quarantine Bureau. The main drafters of this standard. Yong-Hua Guo, Wang Jianling, Chen Tong, Wu Yun Qing. Adhesives, inks, coatings formulations Six Determination of temperament linked phthalates usage

1 Scope

This standard specifies the adhesives, inks, coatings formulations phthalic acid di (2-ethylhexyl) phthalate (DEHP), dibutyl phthalate Ester (DBP), phenyl butyl phthalate (BBP), diisononyl phthalate (DINP), di-n-octyl phthalate (DNOP), Diisodecyl phthalate (DIDP) Content of GC-MS detection method. This standard applies to adhesives, inks, coatings formulations phthalic acid di (2-ethylhexyl) phthalate (DEHP), dibutyl phthalate Ester (DBP), phenyl butyl phthalate (BBP), diisononyl phthalate (DINP), di-n-octyl phthalate (DNOP), Diisodecyl phthalate ester determination (DIDP) is.

2 Method summary

Using hexane as the extraction solvent, ultrasonic sample extract was filtered through qualitative filter paper (if needed), after constant volume through the membrane, gas Chromatography - mass spectrometry was measured internal standard. CAS number six kinds of phthalates and the formula given in Appendix A.

3 Reagents and materials

Unless otherwise specified, the reagents used were of analytical grade should be. 3.1 n-hexane. 3.2 dibutyl phthalate (DBP) standard. Purity ≥97%. 3.3 phenyl butyl phthalate (BBP) Standard. Purity ≥97%. 3.4 phthalate, di (2-ethylhexyl) phthalate (DEHP) Standard. Purity ≥97%. 3.5 phthalate, di-n-octyl phthalate (DNOP) Standard. Purity ≥97%. 3.6 diisononyl phthalate (DINP) Standard.
