Cilësia e tokës - Përcaktimi me gaz-kromatografi i përmbajtjes së hidrokarbureve flurore aromatike ; naftalenit dhe hidrokarburet flurore të halogjenuara - Metoda “purge-trap” me desorbim termik (ISO 15009:2012)

Soil quality - Gas chromatographic determination of the content of volatile aromatic hydrocarbons, naphthalene and volatile halogenated hydrocarbons - Purge-and-trap method with thermal desorption (ISO 15009:2012)

Scope

This International standard specifies a method for quantitative gas-chromatographic determination of volatile 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 determination 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 determinations apply (expressed on basis of dry matter): Typical limit of determination when using GC-FID: Volatile aromatic hydrocarbons: 0,1 mg/kg Typical limit of determination when using GC-ECD: Volatile halogenated hydrocarbons: 0,01 mg/kg. Lower limits of determination for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection.
