Water quality - Determination of hydrocarbon oil index - Part 2: Method using solvent extraction and gas chromatography (ISO 9377-2:2000); German version EN ISO 9377-2:2000
The document specifies a method for the determination of hydrocarbon oil index in water by gas chromatography. The method is suitable for drinking water, surface water, waste water and water from sewage treatment plants and allows the determination of hydrocarbon oil index in concentrations above 0,1 mg/1. The method does not apply to the quantitative determination of the content of volatile mineral oil. On the basis of the peak pattern of the gas chromatogram some qualitative information on the composition of the mineral oil contamination can be derived.#,,#
