This method is for determining individual C6 through C10 aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of 210 degrees C or lower. C11 and heavier aromatics are reported as a group. C10 and heavier non-aromatics, if present in appreciable quantities, may interfere with the determination of benzene and toluene. When this occurs, benzene and toluene can be determined by ASTM D 4420. Other applications include the assay of any C10 or lower boiling aromatics, such as benzene, toluene, 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-%.
