22/30444882 DC

This standard 22/30444882 DC BS EN 17813. Environmental matrices. Halogens and sulfur by oxidative pyrohydrolytic combustion followed by ion chromatography detection and complementary determination methods is classified in these ICS categories:

• 71.040.40 Chemical analysis
• 71.040.50 Physicochemical methods of analysis

This document specifies a method for the simultaneous direct determination of the total fluorine, chlorine, bromine and sulfur content in environmental solid matrices. The method is applicable for the determination of concentrations ≥ 10 mg/kg of each element based on dry matter. The upper limit and exact concentration range covered depend on system blank levels of instrumentation and capacity of the chromatographic separation column used for determination. NOTE Simultaneous determination of total iodine content is possible but currently not validated.
