National Food Safety Standard - Food Contact Materials and Articles -Determination of Diaminomethylbezen in Complex Food Contact Materials and Articles
1 Scope
This standard specifies the determination methods of diaminomethylbezen of complex for food packaging material.
This standard is applicable to the determination of diaminomethylbezen of complex for food packaging material.
Method I Gas Chromatography
2 Principle
Leach the diaminomethylbezen in the specimen with 4% acetic acid solution, cool the leach solution, extract with dichloromethane under alkaline condition, add heptafluorobutyric anhydride (HFBA) for derivatization, inject the derivative into a gas chromatograph equipped with electron capture detector for determination, and carry out the qualitative determination by retention time and quantitative determination by external standard method.
3 Reagents and Materials
Unless otherwise specified, analytically-pure reagents and Class-III water (defined in GB/T 6682) are adopted for the purpose of this method.
3.1 Reagents
3.1.1 Dichloromethane (CH2Cl2): chromatographically pure.
3.1.2 Tert-butyl methyl ether (C5H12O): chromatographically pure.
