The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.
The plastic material of the test substance to food and food simulants specific migration of SN/T 2280 plastic food contact materials is limited
Methods and determination of exposure to food simulants and conditions of selection guidelines
Principle 3
1,3-benzene-soluble mimetics sample dimethylamine, after fluorescent secondary amine derivatives, using high performance liquid chromatography with fluorescence detector
Determination.
1,3-xylylenediamine specimen in olive oil (mass concentration) aqueous acetic acid solution after extraction was determined by the same method with 3%.
Due to the reduced amount of fluorescence amines can generate a second derivative appears single peak in HPLC, using this feature can be 1,3-dimethyl benzene
Amine confirm.
