DIN EN 15308:2016-12 EN 15308:2016 (E) 5 Introduction Polychlorinated biphenyls (PCB) have been widely used as additives in industrial applications where chemical stability has been required. This stability on the other hand creates environmental problems
30、when PCBs are eventually released into the environment. Since some of these PCB compounds are highly toxic, their presence in the environment (air, water, soil, sediment and waste) is regularly monitored and controlled. At present determination of PCB is carried out in these matrices in most of the
31、routine laboratories following the preceding steps for sampling, pretreatment, extraction, clean-up by measurement of specific PCB by means of gas chromatography in combination with mass spectrometric detection (GC-MS) or gas chromatography with electron capture detector (GC-ECD). Taking into accoun
32、t the different matrices and possible interfering compounds, this European Standard does not contain one single possible way of working. Several choices are possible, in particular relating to clean-up. Detection with both Mass Spectrometry and Electron Capture is possible. Two different extraction
33、procedures and nine clean-up procedures are described. The use of internal and injection standards is described in order to have an internal check on choice of the extraction and clean-up procedure. This European Standard has been validated on seven solid waste which are typically contaminated with
34、PCB (building debris, cable shredder, contaminated soil, electronic waste, sealant waste, shredder light fraction and waste wood). Validation data are given in Annex A (informative). DIN EN 15308:2016-12 EN 15308:2016 (E) 6 1 Scope This European Standard specifies a method for quantitative determina
35、tion of seven polychlorinated biphenyl congeners (PCB-28, PCB-52, PCB-101, PCB-118, PCB-138, PCB-153 and PCB-180) in solid waste using high-resolution gas chromatography with electron capture or mass spectrometric detection. The basic content of this standard is identical to that of the Horizontal P
36、CB-standard and is therefore also applicable to soil, sludge and treated bio-waste. The detection and the quantification limits in this method are dependent on sample intake, the level of interferences as well as instrumental limitations. Under the conditions specified in this standard, minimum amou
37、nts of individual PCB congeners equal or above 0,01 mg/kg dry matter can typically be determined with no interferences present. NOTE For the analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to EN 61619, EN 127661 and EN ISO 6468 respectively. The m
38、ethod may be applied to the analysis of other PCB congeners not specified in the scope, but its suitability should be proven by proper in-house validation experiments. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensab

47、nciple A proper test portion is extracted with a mixture of organic solvents by an appropriate extraction technique (e.g. shaking, soxhlet, sonication), partitioned against water and the organic layer separated. The obtained extracts are concentrated and, if appropriate, cleaned-up. Sample clean-up
48、procedures may include sulphuric acid treatment, Dimethylsulfoxide/n-Hexan partitioning, column chromatography on alumina and silica. Tetrabutylammonium sulfite (TBA) or copper may be used to remove sulfur if required. The extract is analysed by gas chromatography with either mass spectrometric (GC-
49、MS) or electron capture detection (GC-ECD). In case of GC-MS analysis quantification is performed by the isotope dilution technique. In case of GC-ECD, extracts are analysed using two columns of different polarity. Quantification is conducted by the internal standard method. In case of plastic shredder a pure non-polar solvent should be used for extraction to prevent dissolving of the polymer matrix as far as possible. DIN EN 15308:2016-12 EN 15308:2016 (E) 8
