ISO 17211:2015描述了对烟囱或管道中携带的烟气中夹带的气相和固相硒化合物进行采样和测定的方法。烟气中的硒含量表示为烟气中元素硒的质量浓度。 颗粒和气态硒化合物分别由过滤器和吸收剂溶液捕获。烟气中硒化合物的总浓度表示为两种浓度之和。 使用电感耦合等离子体发射光谱法(ICP-OES)、电感耦合等离子体质谱法(ICP-MS)或石墨炉原子吸收光谱法(GFAAS)测定两个样品中的硒浓度。也可以使用与原子光谱法耦合的氢化物发生（HG）技术，例如HG-原子吸收光谱法、汞原子荧光光谱法、汞ICP-OES法和汞ICP-MS法。 在0.12 m3的取样体积下，使用HG-ICP-MS对气态硒化合物的检测限为0.3 μ g/m3。在2.0 m3的取样体积下，使用该技术对颗粒状硒化合物的检测限为0,001 2 μ g/m3。

ISO 17211:2015 describes the method for the sampling and determination of selenium compounds in both vapour phase and solid phase that are entrained in flue gases carried in stacks or ducts. The selenium content in flue gas is expressed as a mass concentration of elemental selenium in the stack gas. Particulate and gaseous selenium compounds are captured by a filter and an absorber solution, respectively. The total concentration of selenium compounds in flue gas is expressed as the sum of both concentrations. The concentrations of selenium in both samples are determined using inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS) or graphite furnace atomic absorption spectrometry (GFAAS). Hydride generation (HG) techniques coupled to atomic spectrometry can also be used such as HG-AAS, HG-AFS (atomic fluorescence spectrometry), HG-ICP-OES and HG-ICP-MS. The detection limit for gaseous selenium compounds is 0,3 μg/m³ using HG-ICP-MS at a sampling volume of 0,12 m³. The detection limit for particulate selenium compounds is 0,001 2 μg/m³ using this technique at a sampling volume of 2,0 m³.
