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/kgTypical limit of quantification when using GC-ECD:- Volatile halogenated hydrocarbons: 0,01 mg/kgLower limits of quantification for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection.
