GB 31604.19-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Caprolactam and Determination of Migration (English Version)
1 Scope
This standard specifies the determination method of caprolactam and migration in food contact materials and articles.
This standard is applicable to the determination of caprolactam and migration in food contact materials and articles.
Determination of Caprolactam
2 Principle
Extract the specimen with water, dissolve caprolactam in the extracting solution, filter through the membrane, detect with high performance liquid chromatograph equipped with ultraviolet detector, and carry out the quantative determination by external standard method.
3 Reagents and Materials
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 Reagent
Acetonitrile (C2H3N, CAS No.: 75-05-8): chromatographically pure.
