The method provides accurate quantitative data for tetra- to decachlorobiphenyls and tetra- to octachloro-dibenzo-p-dioxins/dibenzofurans (total concentrations for each isomeric series). It is capable of detecting 0,2 pg/m3 or lower concentrations of most PCBs and PCDFs/PCDDs with air sampling volumes up to 360 m3 or more in special cases. However, it may not be possible to detect all analytes at 0,2 pg/m3 or lower, especially at lower sampling volumes.
Precision under normal conditions can be expected to be ±25 % or better and uncertainty ±50 % or better.
