本技术规范规定了气相色谱质谱法测定的方法 饮用水和地面中多环烃和农药残留的光谱检测（GC-MS） 质量浓度高于0005μg/l的水和质量浓度的地表水和废水 高于0.01μg/l（每种化合物）。 该方法适用于多环芳烃（PAH）和农药以外的非极性物质 残留物。然而，有必要验证该方法对这些化合物的适用性。 注1:ISO/TS 13530中规定了可能适用于该验证的方法。[3] 本技术规范可用于悬浮物含量高达150 mg/l的样品。 注2:使用GC-MS测定多环芳烃属于ISO 28540的范围。[9]

This Technical Specification specifies a method for the determination by gas chromatography with mass spectrometric detection (GC-MS) of polycyclic hydrocarbons and pesticide residues in drinking water and ground water at mass concentrations above 0,005 μg/l and surface water and waste water at mass concentrations above 0,01 μg/l (for each single compound). This method can apply to non-polar substances other than polycylic aromatic hydrocarbons (PAH) and pesticide residues. However, it is necessary to verify the applicability of this method for these compounds. NOTE 1 A potentially suitable method for this verification is specified in ISO/TS 13530.[3] This Technical Specification can be used for samples containing up to 150 mg/l of suspended matter. NOTE 2 Determination of PAH using GC-MS lies within the scope of ISO 28540.[9]
