23、DIN EN 16453:2014-06 EN 16453:2014 (E) 4 1 Scope This European Standard specifies an analytical test method for the determination of phthalates in water, solvent and modified polyphenylene oxide (MPPO) extracts of paper and board materials and articles intended for food contact using gas chromatogra
24、phy coupled to mass spectrometry (GC-MS). This method is applicable to the determination of phthalates in concentration ranging from 0,025 mg/l to 0,5 mg/l for water and solvent extracts and 0,002 mg/dm2to 0,040 mg/dm2for MPPO migration depending on the individual substance, the specified volume use
25、d for analysis and the value of the blank.

30、ing gas chromatography/mass spectrometry (ISO 18856) 3 Principle 3.1 General Phthalates in the test extract from paper and board materials are determined by gas chromatography / mass spectrometry. The test extract is prepared from water, organic solvent and/or MPPO simulant according to respectively
31、: EN 645, EN 647, EN 15519, EN 14338. Other phthalates, as listed in Table 1, may also be analysed by this procedure but it is necessary to determine its applicability in each case. 3.2 Interferences Due to their use as plasticizer agents, phthalates are ubiquitous. Therefore, pay special attention
32、to avoid any contamination. In order to avoid interferences and cross contamination, do not use plastics materials (tubes etc.). Cross contamination is likely to occur with laboratory air. Therefore, remove as far as possible, plastic materials from the laboratory. Cleaning agents often contain phth
33、alates and may severely contaminate the laboratory air if in use regularly. Therefore, refrain from using these agents during application of this procedure. Phthalates may bleed from the septa of the injector port into the gas chromatograph, therefore use septa that are not likely to contaminate the
34、 system. Fittings of syringes or equipment and septa of the sampling bottles may as well contain phthalates. 4 Materials 4.1 General Common laboratory glassware, rinsed with ethyl acetate before use. After rinsing the glassware with solvent, let residual solvent evaporate under a fume hood. In case
35、of contamination, special attention should be paid to the volumetric flasks cleaning. For example the non-volumetric glassware could be cleaned in a furnace at 500C for at least 6 h. Glassware for volumetric purpose can change its properties due to the heating process and so should not be treated th
36、us. Phthalates are ubiquitous laboratory contaminants. Each lot of reagent used for this method should be checked for phthalates contamination.

If required, take a separate sample for the determination of the grammage in accordance with EN ISO 536 and/or for the determination of dry matter content with EN ISO 638. For any storage or transport between sampling and analysis, protect the sample from contamination by using for example aluminium foil to over-wrap DIN EN 16453:2014-06 EN 16453:2014 (E) 8 8 Preparation of the
