Standard Test Method for Total Olefins in Spark-ignition Engine Fuels by Multidimensional Gas Chromatography

Importancia y uso:

5.1 The quantitative determination of olefins in spark-ignition engine fuels is required to comply with government regulations.

5.2 Knowledge of the total olefin content provides a means to monitor the efficiency of catalytic cracking processes.

5.3 This test method provides better precision for olefin content than Test Method D1319. It also provides data in a much shorter time, approximately 20 min following calibration, and maximizes automation to reduce operator labor.

5.4 This test method is not applicable to M85 or E85 fuels, which contain 85 % methanol and ethanol, respectively.
