标准范围

ISO 16703:2004规定了通过气相色谱法定量测定田间潮湿土壤样品中矿物油（烃）含量的方法。该方法适用于100 mg/kg至10 000 mg/kg土壤中的矿物油含量（质量分数），以干物质表示，并可适应较低的检测限。ISO 16703:2004适用于沸点范围为175℃至525℃的所有碳氢化合物、C10H22至C40H82的正构烷烃、异烷烃、环烷烃、烷基苯、烷基萘和多环芳香族化合物的测定，前提是它们在净化过程中不被指定的色谱柱吸收。ISO 16703:2004不适用于源自汽油的

ISO 16703:2004 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 10 000 mg/kg soil, expressed as dry matter, and can be adapted to lower detection limits.ISO 16703:2004 is applicable to the determination of all hydrocarbons with a boiling range of 175 °C to 525 °C, n-alkanes from C₁₀H₂₂ to C₄₀H₈₂, isoalkanes, cycloalkanes, alkylbenzenes, alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified column during the clean-up procedure.ISO 16703:2004 is not applicable to the quantitative determination of hydrocarbons < 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 achieved.
