- 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.
