Rubber — Determination of total sulfur content by ion chromatography
Preview
Summary
This document specifies a method for the determination of the total sulfur content of raw rubber and
unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of a
sample solution using either a tubular furnace combustion or an oxygen combustion flask method.
The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1 % as
it is possible that the oxygen combustion flask method will not give sufficiently accurate results.
The oxygen combustion flask method is not applicable to rubbers containing a metal salt that forms an
insoluble metal sulfate, such as barium sulfate (CAS 7727-43-7).
