ISO 11338-2:2003规定了烟囱和废气中气相和颗粒相多环芳烃（PAH）测定的样品制备、清理和分析程序。分析方法能够检测每立方米样品中亚微克浓度的多环芳烃，具体取决于多环芳烃的类型和取样的烟气量。 ISO 11338-2:2003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，并规定了烟囱和废气中多环芳烃取样的最低要求。

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.
