Content DescriptionISO 22155:2016 specifies a static headspace method for quantitative gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected aliphatic ethers in soil. ISO 22155:2016 is applicable to all types of soil. The limit of quantification is dependent on the detection system 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 quantifications apply (expressed on basis of dry matter). Typical limit of quantification when using GC-FID: - volatile aromatic hydrocarbons: 0,2 mg/kg; - aliphatic ethers as methyl tert.-butyl ether(MTBE) and tert.-amyl methyl ether (TAME): 0,5 mg/kg. Typical limit of quantification when using GC-ECD: - volatile halogenated hydrocarbons: 0,01 mg/kg to 0,2 mg/kg. Lower limits of quantification for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection (see Annex D). About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
