ISO 27108:2010规定了通过固相微萃取（SPME）和气相色谱-质谱（GC？MS）测定饮用水、地下水和地表水中所选植物处理剂和杀生物剂产品的溶解量的方法。测定极限取决于基质、待分析的特定化合物和质谱仪的灵敏度。对于ISO 27108:2010适用的大多数植物处理剂和杀生物剂，其浓度至少为0.05μg/l。实验室间试验证明了与0.05μg/l和0.3μg/l浓度范围相关的验证数据。 该方法可能适用于ISO 27108:2010未明确涵盖的其他化合物或其他类型的水。然而，有必要验证这种方法对这些特殊情况的适用性。

ISO 27108:2010 specifies a method for the determination of the dissolved amount of selected plant treatment agents and biocide products in drinking water, ground water and surface water by solid？phase microextraction (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 plant treatment agents and biocides to which ISO 27108:2010 applies, it is at least 0,05 μg/l. Validation data related to a concentration range between 0,05 μg/l and 0,3 μg/l have been demonstrated in an interlaboratory trial. This method may be applicable to other compounds not explicitly covered by ISO 27108:2010 or to other types of water. However, it is necessary to verify the applicability of this method for these special cases.
