    1. Scope

    This method is for determining total cycloparaffins (naphthenes) and total aromatics in synthetic paraffinic kerosene fuels (SPK) or petroleum distillates in the boiling range of 69C to 350C using comprehensive two-dimensional gas chromatography (GCxGC) coupled with a flame ionization detector (FID). Molecular type groups are identified by their location, as plotted on a chromatographic contour plot image. The precision of this test method has been established for SPK fuels containing from 1.6 to 32.3 mass-% naphthenic hydrocarbons and 0.03 to 1.9 mass-% aromatic hydrocarbons. Alkenes and compounds containing sulfur, nitrogen, and oxygen are possible interferents.
