ISO 17943:2016规定了挥发性有机化合物的测定方法（见表1）。例如，这包括卤代烃、三卤甲烷、汽油组分（如BTEX、MTBE和ETBE）、萘、2-乙基-4-甲基-1,3-二氧戊环，以及饮用水、地下水、地表水和经处理废水中的高气味物质，如geosmin和2-甲基异龙脑，采用顶空固相微萃取（HS-SPME）和气相色谱-质谱（GC-MS）技术。测定极限取决于基质、待分析的特定化合物以及质谱仪的灵敏度。对于本国际标准适用的大多数化合物，其浓度至少为0.01μg/l。与0.02μg/l至2.6μg/l浓度范围相关的验证数据已在实验室间试验中得到证明。 来自标准化工作的其他验证数据表明，该方法适用于0.01μg/l至100μg/l浓度范围内的单个物质。所有测定均以少量样品（例如，10毫升的样品体积）进行。

ISO 17943:2016 specifies a method for the determination of volatile organic compounds (see Table 1). This comprises, for example, halogenated hydrocarbons, trihalogenated methanes, gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane, and highly odorous substances like geosmin and 2-methylisoborneol in drinking water, ground water, surface water, and treated waste water, by means of headspace solid-phase micro-extraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS). The limit of determination depends on the matrix, on the specific compound to be analysed, and on the sensitivity of the mass spectrometer. For most compounds to which this International Standard applies, it is at least 0,01 μg/l. Validation data related to a concentration range between 0,02 μg/l and 2,6 μg/l have been demonstrated in an interlaboratory trial. Additional validation data derived from standardization work show applicability of the method within a concentration range from 0,01 μg/l to 100 μg/l of individual substances. All determinations are performed on small sample amounts (e.g. sample volumes of 10 ml).
