Design of a test for migration studies in the vapour phase

Abstract

A new test for migration studies in the vapour phase has been developed. The system consists of placing the packaging material containing the potential migrants in a glass vial together with the solid adsorbent, Tenax GC. The vial is introduced into an oven at a controlled temperature for different periods of time. Once the migration test has finished, Tenax is extracted by supercritical fluid chromatography (SFE) and analysed by GC‐ECD. Migration conditions of 7 days at 80°C are proposed. The results obtained are discussed.
