GB 31604.37-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Triethylamine and Tributylamine (English Version)
1 Scope
This standard specifies the gas chromatography for the determination of the contents of triethylamine and tributylamine in food contact materials and articles.
This standard is applicable to the determination of triethylamine and tributylamine in polycarbonate food contact materials and articles.
2 Principle
After dissolving the sample with dichloromethane, add in acetone to precipitate the polymer resin; after concentration and scaling of the volume, carry out determination by gas chromatography and quantative determination by external standard method.
3 Reagents and Materials
Unless otherwise specified, analytically-pure reagents are adopted for the purpose of this method. Plastic containers and transfer appliances shall not be used in the test.
3.1 Reagents
3.1.1 Dichloromethane (CH2Cl2).
