Scope
This standard specifies the determination method of gas chromatography for the migration of ethylenediamine and hexamethylene diamine in food contact materials and articles.
This standard is applicable to the determination of migration of ethylenediamine and hexamethylene diamine in food contact materials and articles.
2 Principle
With the ethyl chloroformate as the derivatization reagent, derive the ethylenediamine and hexamethylene diamine in food simulants and transform them into corresponding derived products of dicarbamate ethyl ester, separate by gas chromatographic column, and detect by hydrogen flame ionization detector. Carry out the quantitative determination by internal standard method with 1,3-propylene diamine as the internal standard sbustance.
