GB 31604.27-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Ethylene Oxide and Propylene Oxide in Plastics (English Version)
1 Scope
This standard specifies determination method of ethylene oxide and propylene oxide in food contact materials and articles.
This standard is applicable to determination of ethylene oxide and propylene oxide in plastic food contact materials and articles.
Method I Headspace Gas chromatography-mass Spectrometry
2 Principle
Extract ethylene oxide or propylene oxide in the sample with N, N-dimethyl acetamide (DMAC), conduct headspace sample injection, separate ethylene oxide or propylene oxide and ethyl ether (internal standard) and other components in chromatographic column, examine by mass spectrometry detector and carry out quantative determination by internal 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.
