标准摘要
[中文适用范围]： ISO 11338 的这一部分规定了用于测定烟囱和废气中气体和颗粒相多环芳烃 (PAH) 的样品制备、净化和分析程序。 分析方法能够检测每立方米样品中亚微克浓度的 PAH，具体取决于 PAH 的类型和采样的烟气体积。 ISO 11338 本部分中描述的方法基于高效液相色谱 (HPLC) 或气相色谱-质谱 (GC-MS)。 注：ISO 11338-1 描述了三种方法，并规定了烟道和废气中 PAH 采样的最低要求。 [外文原描述]： ISO 11338-2:2003 specifies procedures for sample preparation, clean-up and analysis for the determination of gas and particle phase polycyclic aromatic hydrocarbons (PAH) in stack and waste gases. The analytical methods are capable of detecting sub-microgram concentrations of PAH per cubic metre of sample, depending on the type of PAH and the flue gas volume sampled. The methods described in ISO 11338-2:2003 are based on either high performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS). NOTE ISO 11338-1 describes three methods and specifies minimum requirements for the sampling of PAH in stack and waste gases.
