Resumen:
This International Standard specifies a method for the determination of mono- to octa-polychlorinated naphthalenes (PCNs) in waters and waste waters (containing less than 2 g/l solid particulate material (SPM)) using high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). The congeners analysed by this method are listed in Table 1. The working range of the method is 20 pg/l to 8 ng/l. The method is optimized for PCNs, but may be modified to include other co-planar compounds such as polychlorinated dioxins and furans (PCDDs/PCDFs) and dioxin-like tetra- to hepta-chlorinated biphenyls (dlPCBs). This method may be used to determine PCNs in other matrices (e. g. biota, sediments, air), however additional clean-up steps and techniques may be required for samples with high organic loadings. Low resolution mass spectrometry (LRMS) and mass spectrometry/mass spectrometry (MS/MS) may be used and conditions are summarized in Annex A. Both LRMS and MS/MS may be less selective than HRMS and there is a possibility of bias due to interfering compounds if these techniques are used.
