25、6703:2011-09 EN ISO 16703:2011 (E) 3 1 Scope 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/k
26、g and 10 000 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 C to 525 C, of n-alkanes from C10H22to C40H82, of isoalkanes, cycloalkanes, alkylbenzenes,
27、 alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified column during the clean-up procedure. This International Standard is not applicable to the quantitative determination of hydrocarbons C40) compounds in the chromatogram; f) any details not spec
28、ified in this International Standard or which are optional, as well as any other factor that might have affected the results.

29、e gas chromatogram of the calibration mixture of mineral oil consisting of equal parts of a diesel fuel and a lubricating oil. Figure A.2 shows the gas chromatogram of the “column bleed” after injection of n-heptane, and Figure A.3 shows the integrated gas chromatogram of the calibration mixture of
30、mineral oil corrected for the “column bleed”. The total peak area between n-decane (C10) and n-tetracontane (C40) used for quantification is indicated as hatched area. The Figures A.4 and A.5 show integrated gas chromatograms corrected for the “column bleed” of low and highly contaminated soil sampl
31、es, respectively. Figure A.6 shows a chromatogram of a system-performance standard solution.
