Scope

This document describes a method for determining hydrocarbons in petroleum fractions with boiling points below 315°C using fluorescent indicator adsorption.
This document is applicable to the determination of total aromatics, total olefins, and total saturated hydrocarbons in petroleum fractions with boiling points below 315°C. The measurement range is: a volume fraction of aromatics of 5% to 99%, a volume fraction of olefins of 1% to 55%, and a volume fraction of saturated hydrocarbons of 1% to 95%. This document can also be used for samples with concentrations outside the above range, but the accuracy has not been determined. This document is not applicable to samples containing dark components that affect the colorimetric reading of hydrocarbons.
This document is applicable to petroleum products over the entire boiling range, but statistical test data show that the accuracy of this document is not suitable for narrow petroleum fractions with boiling points close to 315°C. Such samples cannot be properly separated, and the measurement results are unstable.
This document can also be used for automotive spark-ignition engine fuels (automobile gasoline), containing or not containing oxidized compounds such as alcohols and ethers (e.g., MTBE, ethanol), and where gasoline is the main volume component of the blending components.
This document is applicable to samples containing certain oxidized compounds as blending components. These oxidized compounds include methanol, ethanol, methyl tert-butyl ether (MTBE), tert-amyl methyl ether (TAME), and ethyl tert-butyl ether (ETBE). Their concentrations in general blending products do not affect the determination of hydrocarbons. They elute together with alcohol eluents and are not detected. Other oxidized compounds should be verified individually. When analyzing samples containing oxidized compounds as blending components, the results are corrected based on the entire sample.
