ISO\/TS 16780:2015 specifies a method for the determination of polychlorinated naphthalenes (PCNs), where "poly" means "mono" to "octa", 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).<\/p>\n

NOTE 1 The congeners analysed by this method are listed in Table 1.<\/p>\n

The working range of the method is 20 pg\/l to 8 ng\/l. The method is optimized for PCNs, but can be modified to include other coplanar compounds such as polychlorinated dioxins and furans (PCDDs\/PCDFs) and dioxin-like tetra- to heptachlorinated biphenyls (dlPCBs). This method can be used to determine PCNs in other matrices (e.g. biota, sediments, air); however, additional clean-up steps and techniques can be necessary for samples with high organic loadings. Low resolution mass spectrometry (LRMS) and mass spectrometry?mass spectrometry (MS?MS) can be used.<\/p>\n

NOTE 2 LRMS and MS?MS conditions are summarized in Annex A.<\/p>\n

Both LRMS and MS?MS can be less selective than HRMS and there is a possibility of bias due to interfering compounds if these techniques are used.<\/p>\n

The detection limits and quantification levels in this method are dependent on the level of interferences as well as instrumental limitations.<\/p>\n

NOTE 3 The minimum levels (ML) in Table 4 are the levels at which the PCNs can typically be determined with no interferences present.<\/p>\n

This method is performance based. The analyst is permitted to modify the method, e.g. to overcome interferences, provided that all performance criteria in this method are met.<\/p>\n

NOTE 4 The requirements for establishing method validation or equivalency are given in Clause 9.<\/p>\n","protected":false},"excerpt":{"rendered":"
