20、Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 07/08/2008 03:31, Uncontrolled Copy, (c) BSIEN 15308:2008 (E) 4 1 Scope This document specifies a method for quantitative determination of seven polychlorinated biphenyl congeners (PCB-28, PCB-52, PCB-101, PCB-118, PCB-138, PCB-153 and PCB-180) in solid waste
21、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 PCB-standard and is therefore also applicable to soil, sludge and treated bio-waste. The detection and the quantification limits i
22、n this method are dependent on sample intake, the level of interferences as well as instrumental limitations. Under the conditions specified in this standard, minimum concentrations of individual PCB congeners equal or above 0,01 mg/kg dry matter can typically be determined with no interferences pre
23、sent. NOTE 1 For the analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to EN 61619, EN 12766-1 and EN ISO 6468, respectively. NOTE 2 The method may be applied to the analysis of other PCB congeners not specified in the scope, but its suitability sho
24、uld be proven by proper in-house validation experiments. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (incl
25、uding any amendments) applies. EN 14346, Characterization of waste Calculation of dry matter by determination of dry residue or water content 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 polychlorinated biphenyl PCB biphenyl substituted by
26、 one to ten chlorine atoms 3.2 congener member of the same kind, class or group of chemicals e. g. anyone of the two hundred and nine individual PCB NOTE The IUPAC congener numbers are for easy identification; they do not represent the order of chromatographic elution. 3.3 calibration standard solut

29、 present in waste samples added to the sample extract before injection into the gas chromatograph, to monitor variability of instrument response and the recovery of the internal standards 3.6 critical pair pair of congeners that must be separated to a predefined degree (e. g. R = 0,5) to ensure chro
30、matographic separation meets minimum quality criteria 3.7 resolution Rsdifference in retention times between the maxima of the two peaks i and j, which constitute the critical pair, divided by the arithmetic mean of the peak widths of i and j at base, calculated as: ( )()bjbiRiRjs2wwttR+= (1) where
31、tRjand tRiare the retention times of the two peaks i and j (sec), and wbiand wbjare the peak widths of i and j (sec) at base 4 Principle A proper test portion is extracted with a mixture of organic solvents by an appropriate extraction technique (e. g. shaking, soxhlet, sonication), partitioned agai
32、nst water and the organic layer separated. The obtained extracts are concentrated and, if appropriate, cleaned-up. Sample cleanup procedures may include sulphuric acid treatment, Dimethylsulfoxide/n-Hexan partitioning, column chromatography on alumina and silica. Tetrabutylammonium sulfite (TBA) or
33、copper may be used to remove sulfur if required. The extract is analyzed by gas chromatography with either mass spectrometric (GC-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 analy
34、zed using two columns of different polarity. Quantification is conducted by the internal standard method. NOTE 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. 5 Reagents 5.1 General All reagents shall
35、be of recognized analytical grade. Running a blank determination as described in 11.1 shall check the purity of the reagents used. 5.2 Reagents for extraction and drying 5.2.1 Acetone. 5.2.2 Hexane like solvents with a boiling range of 36 C to 98 C, e. g. petroleum ether, n-hexane, n-heptane.
