Rubber. Identification of polymers. Pyrolytic gas-chromatographic method using mass-spectrometric detection1 Scope This document provides a qualitative method for the identification of rubbers by their pyrolysis products using tandem gas chromatography mass spectrometry. The method applies to rubbers in the raw state and to unvulcanized and vulcanized compounds. Compounds can be based on a single rubber or a blend of two or more rubbers. Where the level of a particular rubber in a blend is <10 %, detection and identification can be difficult. A non
