GB 31604.28-2016 National Food Safety Standard - Food Contact Materials and Articles - Determination of Di(2-ethylhexyl)adipate and Determination of Migration (English Version)
1 Scope
This standard specifies determination method of di(2-ethylhexyl)adipate (DEHA) in food contact materials and articles and its migration.
This standard is applicable to determination of di(2-ethylhexyl)adipate in polyvinyl chloride products and its migration.
Determination of Di(2-ethylhexyl)adipate
2 Principle
Dissolve the specimen with tetrahydrofuran, add in methanol to precipitate the polymers in it, with DEHA left in the filtrate. Determine with the gas chromatography-mass spectrometer and carry out the quantative determination by external standard method.
3 Reagents and Materials
3.1 Reagents
Unless otherwise specified, analytically-pure reagents and Class-I water (defined in GB/T 6682) are adopted for the purpose of this method.
3.1.1 Tetrahydrofuran (C4H8O, CAS No.: 109-99-9).
3.1.2 Methanol (CH4O, CAS No.: 67-56-1).
3.1.3 N-hexane (C6H12, CAS No.: 110-54-3): chromatographically pure.
