GB 31604.26-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Epichlorohydrin and Determination of Migration (English Version)
1 Scope
This standard specifies the determination method of epichlorohydrin in food contact materials and articles (plastic, paint, paper and board) and determination method of migration.
This standard is applicable to determination method of epichlorohydrin in food contact materials and articles (plastic, paint, paper and board) and determination method of migration of epichlorohydrin, therein, high performance liquid chromatography is applicable to determination of epichlorohydrin in food contact materials and articles (plastic, paint and paper product) while gas chromatography-mass spectrometry is applicable to determination of migration of epichlorohydrin in food contact materials and articles (plastic, paint, paper and board).
Determination of Epichlorohydrin
2 Principle
Extract epichlorohydrin in the specimen with 1,4-dioxane, distill extracting solution by micro-distillation apparatus, derive epichlorohydrin in distillate, separate derivative by liquid chromatography, determine content of epichlorohydrin derivative by fluorescence detector and convert into content of epichlorohydrin in the specimen. Carry out quantitative determination by external standard method.
