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. C10 and 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 C10 or 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).
