标准范围

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 a basis of dry matter):a) Typical limit of determination when using gas chromatography/flame ionization detection (GC/FID):— volatile aromatic hydrocarbons: 0,1 mg/kg.b) Typical limit of determination when using gas chromatography/electron capture detector (GC/ECD):— volatile halogenated hydrocarbons: 0,01 mg/kgLower limits of determination for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection.
