INTERLABORATROY COMPARISON FOR THE MEASUREMENT OF BROMINE CONTENTS IN PLASTIC SAMPLES USING COMBUSTION ION CHROMATOGRAPHY

摘要

An interlaboratory comparison study was performed. It was on the determination of bromine contents in plastic samples by using electric furnace combustion ion chromatography (C-IC) method, which had been proposed a new Korean standard procedure for the measurement of halogen (bromine, chlorine, fluorine). Two candidate reference materials were used as test materials. Range of bromine contents in the materials was 100-1 000 mg/kg. Instrumental neutron activation analysis was applied to determine the bromine contents in the materials, which were used as the reference values of thhis study. 14 voluntary laboratories from electronics manufacturing companies, testing companies, governmental bodies participated in the study.
