Halogens in a polymer sample applying Metrohm Combustion IC according to RoHS

Introduction

The Restriction of Hazardous Substances Directive (RoHS) requires to reduce the halogen content in several organic materials used in electrical and electronic equipment. In this context, there is a huge interest for using halogen-free polymers. To check for halogens in polymers, Metrohm Combustion IC applying flame sensor technology and Inline Matrix Elimination is an indispensable method. The examined polymeric material contains halogens at a level of up to 1%.
