Scope: This document describes a method for the determination of the total sulfur content of raw and vulcanized rubber or rubber mixes by ion chromatography, with sample solutions prepared by combustion in a tube furnace or by combustion in an oxygen flask. The tube furnace combustion method is suitable for rubber samples with a total sulfur content of less than 0.1%, because the determination results of the oxygen bottle combustion method may not be accurate enough. The oxygen bottle combustion method is not suitable for rubber containing metal salts and forming insoluble metal sulfates [such as barium sulfate (CAS7727 43 7)].
