BS EN ISO 22854:2008 Liquid petroleum products. Determination of hydrocarbon types and oxygenates in automotive-motor gasoline. Multidimensional gas chromatography method

BS EN ISO 22854 specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline.  Additionally, the benzene content, oxygenate compounds and total oxygenate content can be determined.

BS EN ISO 22854 applies to automotive motor gasoline with a total content of aromatics of up to 50 %; a total olefin content from about 1,5 % up to 30 %; oxygenate compounds, from 0,8 % up to 15 %; a total oxygen content from about 1,5 % to about 3 %; and a benzene content of up to 2 %.

Although specifically developed for the analysis of automotive motor gasoline that contains oxygenates, this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.
