填充油中多环芳烃含量测试新标准EN 16143:2013解读

New Standard Test Method EN 16143:2013 for Determination of Content of Polycyclic Aromatic Hydrocarbons(PAHs) in Extender Oils

对欧盟填充油中多环芳烃(PAHs)含量测试新标准EN 16143:2013进行解读,并与标准IP 346:1998进行对比。EN 16143:2013测试方法为:通过双液相清洗填充油,使其复杂基质得到净化,利用气相色谱/质谱联用仪对填充油中的苯并(a)芘含量及8种PAHs总含量进行直接测试。与IP 346:1998测试方法相比,EN 16143:2013测试方法的谱峰分离效果好,测试结果更准确。EN 16143:2013已经开始实施,将取代IP 346:1998。

The new standard EN 16143 ： 2013 for the determination of the content of polycyclic aromatic hydrocarbons （PAHs） in extender oils in the European Union is interpreted and compared with the standard IP 346： 1998.In the EN 16143：2013 test, the extender oil is purified by two-liquid phases separation and the content of benzo （a） pyrene and 8 kinds given PAHs are directly determined by gas chromatography/mass spectrometry.Compared with IP 346： 1998, EN 16143：2013 test method gives better peak separation result and more accurate test result.EN 16143：2013 has been implemented and will eventually replace IP 346： 1998.
