Scope: This standard specifies the method for the separation and determination of middle distillates, including aromatic components, non-aromatic components and fatty acid methyl ester components in diesel oil containing fatty acid methyl esters, by solid-phase extraction-gas chromatography. This standard is applicable to the middle distillate with a distillate range of 170 ℃ ~ 400 ℃, including diesel oil containing fatty acid methyl ester volume fraction less than 10%. This standard is divided into Method 1 and Method 2. Method 1 is applicable to middle distillate without fatty acid methyl ester, and method 2 is applicable to diesel oil containing fatty acid methyl ester volume fraction less than 10%. This standard is applicable to the determination of middle distillate samples containing 4%~50% mass fraction of aromatic components, and diesel samples containing 2%~10% volume fraction of fatty acid methyl ester components. Samples beyond this content range can also be determined by this standard, but no precision data is given. When analyzed according to method 1 of this standard, aromatic hydrocarbons include thiophene sulfur-containing compounds, nitrogen-containing compounds and oxygen-containing compounds; when analyzed according to method 2 of this standard, nitrogen-containing compounds and oxygen-containing compounds are included in fatty acid methyl ester components, which may affect the result.
