1 Scope

This document describes a high performance liquid chromatography-tandem mass spectrometry method for the determination of the migration of N-nitrosamines and their precursors in the following toys and toy materials Spectrum. --- Elastomeric toys and toy elastomer parts. --- Refers to paint. Example. Elastomeric toys such as balloons and gutta-percha. Note. For elastomer materials, N-nitrosamines and their precursors are mainly detected in vulcanized materials. This document is applicable to the determination of the migration of 13 kinds of N-nitrosamines and their precursors in the above toys and toy elastomer materials. other The detection of N-nitrosamines and their precursors can be carried out with reference to this document after verification.
