This document describes the test method for determining the hydrocarbon composition and benzene content in light petroleum fractions and products using multidimensional gas chromatography technology.
This document is applicable to the determination of hydrocarbon composition and benzene content in light petroleum fractions and products (such as gasoline, gasoline blending components, solvent oils, etc.) with a final distillation point not exceeding 215 °C. The measurement concentration range for olefins is 0.5% to 70% by volume (0.4% to 64% by mass), for aromatics it is 1% to 80% by volume (1.2% to 92% by mass), and for benzene it is 0.2% to 10% by volume (0.2% to 12% by mass). For samples with measured concentrations exceeding the above ranges, the precision has not been determined yet.
This document is also applicable to gasoline products obtained from other unconventional crude oils such as shale or oil sands, or hydrocarbon fuels synthesized from non-petroleum mineral fuels like Fischer-Tropsch synthesis oil, but the precision for these samples has not been determined yet.
