IS 1448 : Part 119 : 1985 Methods of test for petroleum and its products: Part 119 Aromatic traces in light saturated hydrocarbons by Gas chromataography

1 Scope

1.1 This method covers the determination of benzene, toluene,and C₈ aromatics in light saturated hydrocarbonsamples. The method is limited by aromatic selectivity of thestationary liquid to samples containing n-decane as the highestboiling compound. (see Note).

Note - Some of the C₁₀naphthenes have boiling points below that of n-decane. Suchcompounds may be eluted after n-decane on the columns described inthis method and may cause interference with the determination ofbenzene.

1.2 The method covers the concentration range from 0.005 to 1.00volume percent of each C₆ to C₆aromatic carbon number group.

1.3 Results are reported to two significant figures.
