Water quality. Determination of tetra- to octa-chlorinated dioxins and furans. Method using isotope dilution HRGC/HRMS Ingestion-build-78747 For a narrowband source1 Scope This International Standard specifies a method for the determination of tetra to octa chlorinated dibenzo p dioxins (PCDDs) and dibenzofurans (PCDFs) in waters and waste waters (containing less than 1 % by mass solids) using high resolution gas chromatography high resolution mass spectrometry (HRGC HRMS). This International Standard is applicable to the seventeen 2,3,7,8 substituted PCDDs PCDFs specified in Table 1. The detection limits and
