Indoor air — Part 14: Determination of total (gas and particle-phase) polychlorinated dioxin-like biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDDs/PCDFs) — Extraction, clean-up and analysis by high-resolution gas chromatography and mass spectrometry

ISO 16000-14:2009 specifies extraction, clean-up, and analysis procedures for the determination of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) collected from indoor air on particle filters backed by polyurethane foam (PUF). The method incorporates specific analyses by high resolution gas chromatography combined with high resolution mass spectrometry (HRGC/HRMS).

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.
