Liquid petroleum products - Determination of hydrocarbon types and oxygenates in automotive-motor gasoline - Multidimensional gas chromatography method (ISO 22854:2008); English version of DIN EN ISO 22854:2009-01
This International Standard 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.
This International Standard is applicable to automotive motor gasoline with a total content of aromatics of up
to 50 % (V/V); a total olefin content from about 1,5 % (V/V) up to 30 % (V/V); oxygenate compounds, from
0,8 % (V/V) up to 15 % (V/V); a total oxygen content from about 1,5 % (m/m) to about 3 % (m/m); and a
benzene content of up to 2 % (V/V).
NOTE 1 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used the represent, respectively,
the mass fraction and the volume fraction.
NOTE 2 While developing this method, the final boiling point was limited to 215 ~C.
NOTE 3 For oxygenate compounds, precision data have been established on automotive motor gasoline samples
containing ethyl-tert-butyl ether (ETBE), methyl-tert-butyl ether (MTBE), tert-amyl-methyl ether (TAME), iso-propanol, iso-
butanol, tert-butanol, methanol and ethanol. The derived precision data for methanol do not comply with the precision
calculation as presented in this International Standard. Applicability of this International Standard has also been verified for
the determination of n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been
determined for these compounds.
Although this test method can be used to determine higher-olefin contents of up to 50 % (V/V), the precision
for olefins was tested only in the range from about 1,5 % (V/V) to about 30 % (V/V).
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.
NOTE 4 There can be an overlap between C9 and C10 aromatics. However, the total is accurate. Isopropyl benzene is
resolved from the C8 aromatics and is included with the other C9 aromatics.
