BS EN 17813:2023

This standard BS EN 17813:2023 Environmental solid matrices. Determination of halogens and sulfur by oxidative pyrohydrolytic combustion followed by ion chromatography is classified in these ICS categories:

• 71.040.40 Chemical analysis
• 71.040.50 Physicochemical methods of analysis

This document specifies an empirical method for the simultaneous direct determination of the fluorine, chlorine, bromine, and sulfur content in environmental solid matrices by oxidative pyrohydrolytic combustion at (1 050 ± 50) °C, followed by ion chromatography. 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 depends on the blank levels of the instrumentation and the capacity of the chromatographic separation column used for determination. NOTE 1 Simultaneous determination of iodine content is possible but currently not validated. NOTE 2 Other detection methods can be applied if validated.
