P Vp C toys and childcare articles of 6 phthalic Dicarboxylate measured by gas chromatography - mass spectrometry1 ScopeThis standard specifies the gas chromatographic PVC toys and childcare articles in six kinds of phthalates - mass spectrometry methods. This standard applies to the determination of PVC toys and childcare articles in six kinds of phthalates.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Containing PVC (polyvinyl chloride) toys and children's products. Principle 3 Sample using ethyl acetate as the extraction solvent, the extraction, after extraction fluid volume by gas chromatography - mass spectrometry determination, internal standard method Quantified. English name six kinds of phthalates, CAS number, and the formula given in Appendix A.4 Reagents and materialsUnless otherwise specified, the reagents used were of analytical grade should be. 4.1 ethyl acetate. 4.2-n-butyl phthalate (DBP) standard. Purity ≥97%. 4.3 phthalate, butyl benzyl phthalate (BBP) Standard. Purity ≥97%. 4.4 bis (2-ethylhexyl) phthalate (DEHP) standard. Purity ≥97%. 4.5 phthalate, di-n-octyl phthalate (DNOP) Standard. Purity ≥97%. 4.6 diisononyl phthalate (DINP) Standard. Purity ≥97%. 4.7 phthalate, diisodecyl phthalate (DIDP) Standard. Purity ≥97%. Phthalate 4.8 standard stock solution. Weigh accurately respectively dibutyl phthalate (DBP) standard (4.2), dibutyl phthalate Benzyl ester (the BBP) standard (4.3), bis (2-ethylhexyl) phthalate (DEHP) standard (4.4) and di-n-octyl phthalate (DNOP) standard (4.5) each 10.0mg, diisononyl phthalate (DINP) standard (4.6) and diisodecyl phthalate (DIDP) standard (4.7) each 100.0mg, were placed in 100mL flask, diluted with ethyl acetate (4.1) to the mark and mix. Mark Quasi stock solution was stored at 0 ℃ ~ 4 ℃ refrigerator valid for 12 months. 4.9 Internal standard. di-n-hexyl phthalate (DHP was). purity ≥97%. 4.10 standard internal standard stock solution. accurately weighed amount of di-n-hexyl phthalate (DHP) standard (4.9), with ethyl (4.1) formulated at a concentration of 100mg/mL standard stock solution. Validity of standard stock solution was stored at 0 ℃ ~ 4 ℃ refrigerator 12 months. 4.11 mixed standard working solution. Apply the standard internal standard stock solution (4.10), phthalates standard stock solution (4.8), according to We need to be diluted into a mixed standard working solution with suitable concentration of ethyl acetate (4.1). Validity of the working solution was kept at 0 ℃ ~ 4 ℃ refrigerator 6 months. 4.12 Internal standard solution. take appropriate internal standard stock solution (4.10), diluted to the appropriate concentration was necessary with ethyl acetate (4.1). ...... |
