适用范围

This International Standard specifies a method for the quantitative determination of the mineral oil (hydrocarbon) content in field-moist soil samples by gas chromatography. The method is applicable to mineral oil contents (mass fraction) between 100 mg/kg and 10000 mg/kg soil, expressed as dry matter, and can be adapted to lower limits of detection. This International Standard is applicable to the determination of all hydrocarbons with a boiling range of 175 ?to 525 ? of n-alkanes from C₁₀H₂₂ to C₄₀H₈₂, of isoalkanes, cycloalkanes alkylbenzenes, alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified column during the clean-up procedure. This International Stanard is not applicable to the quantitative determination of hydrocarbons kleiner C₁₀ originating from gasolines. On the basis of the peak pattern of the gas chromatogram obtained, and of the boiling points of the individual n-alkanes listed in annex B, the approximate boiling range of the mineral oil and some qualitative information on the composition of the contamination can be obtained.
