Abstract: The contents of olefins, aromatics and benzene are the important quality specifications of gasoline. The determination of olefins, aromatics and benzene can be measured by different methods. The characteristics of these methods are compared and analyzed through robin tests. A new method for determination of hydrocarbon types and benzene by multi gas chromatography developed by Research Institute of Petroleum processing （RIPP）is introduced in detail. This method is adopted and published as an international ASTM standard, which is the first international standard set by China in the field of oil and petroleum products.
