This method is for determining individual C₆ through C₁₀ aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of 210°C or lower. C₁₁ and heavier aromatics are reported as a group. C₁₀and heavier non-aromatics may interfere with the determination of benzene and toluene. When this occurs, benzene and toluene can be determined by ASTM Methods D 5443, D 5580, D6729, or D 6839, or UOP Method 690. Other applications for this method include the assay of any C₁₀or lower boiling aromatics, such as benzene, toluene, mixed xylenes, etc. This method may also be used to provide a distribution of C₈ aromatics and/or C₉ and heavier aromatics to a value determined by a different method. When used for any of the above applications, the quantitation limit for a single aromatic component is 0.01 mass-%. The Appendix describes an extension to the method to analyze individual C₆ through C₁₀ aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of less than 344°C (nC₂₀).
