标准摘要
[中文适用范围]： 适用于所有类型的土壤。 在未饱和泥炭质土壤中可能会发生萃取溶液的吸附现象。 定量限取决于所使用的设备和用于样品提取的甲醇的质量。 下限根据本国际标准规定的条件下适用： [外文原描述]： ISO 15009:2016 specifies a method for quantitative gas-chromatographic determination of volatile aromatic hydrocarbons, naphthalene and volatile halogenated hydrocarbons in soil. This International Standard is applicable to all types of soil. NOTE In the case of unsaturated peaty soils, absorption of the extraction solution may occur. The lower limit of quantification is dependent on the equipment used and the quality of the methanol grade used for the extraction of the soil sample. Under the conditions specified in this International Standard the following limits of quantification apply (expressed on basis of dry matter): Typical limit of quantification when using GC-FID: - Volatile aromatic hydrocarbons: 0,1 mg/kg Typical limit of quantification when using GC-ECD: - Volatile halogenated hydrocarbons: 0,01 mg/kg Lower limits of quantification for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection.
