Application Note: Halogens in a Polymer Sample: According to Restriction of Hazardous Substances Directive
4 October 2017
The restriction of hazardous substances directive (RoHS) requires the reduction of 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 Ion Chromatography applies flame sensor technology and Inline Matrix Elimination as an indispensable method. The examined polymeric material contains halogens at a level of up to 1%.
