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 \u00b1 50) \u00b0C, followed by ion chromatography. The method is applicable for the determination of concentrations \u2265 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.<\/p>\n
