The Technical Committee 19 of the European Committee for Standardization (CEN/TC19) in the "Lisbon resolution" requested to evaluate replacement methods to the fluorescent indicator absorption (FIA) (American Standardization for Testing and Material D 1319) method for the determination of aromatics and olefins in gasolines. In the same resolution it was requested to review the two existing methods for the determination of benzene content of gasolines, anticipating lower limit values in future European gasoline specifications. As a result of this request, a round robin (RR) was organized in which 8 gasoline samples are analyzed using 10 different methods in 33 laboratories. The methods used in the RR include, apart from the FIA method, one-dimensional gas chromatography (GC) and multidimensional GC, with and without specific detectors and spectroscopic analysis methods. This study describes these methods in short, gives an evaluation of the results of the RR, and draws a conclusion on the outcome.
欧洲标准化委员会（CEN/TC19）技术委员会19在“里斯本决议”中要求评估用于测定汽油中芳烃和烯烃的荧光指示剂吸收法（FIA）（美国材料与试验协会标准D 1319）的替代方法。在同一决议中，要求审查现有的两种测定汽油苯含量的方法，预期未来欧洲汽油规格会有更低的限值。由于这一要求，组织了一次循环试验（RR），在33个实验室中使用10种不同方法对8个汽油样品进行分析。RR中使用的方法除了FIA法外，还包括一维气相色谱法（GC）和多维GC，有或没有特定检测器以及光谱分析方法。本研究简要描述了这些方法，对RR的结果进行了评估，并就结果得出了结论。
