Standard Test Method for Determination of Benzene in Spark-Ignition Engine Fuels Using Mid Infrared Spectroscopy.
Get more information about the standard at ASTM D6277-07(2022).
ASTM D6277 is a standard test method for determining the benzene content in spark-ignition engine fuels using mid-infrared (IR) spectroscopy. Benzene, a known health hazard, is regulated in gasoline to minimize environmental and health risks. This method provides a rapid, simple, and cost-effective approach to quantify benzene concentrations, ensuring compliance with regulatory standards.
Details
The ASTM D6277 test method is applicable for measuring benzene concentrations ranging from 0.1% to 5% by volume in spark-ignition engine fuels. The procedure involves analyzing a fuel sample using mid-IR spectroscopy, which identifies benzene based on its characteristic absorption bands in the mid-infrared region. This technique allows for the rapid and accurate quantification of benzene content without the need for extensive sample preparation.
The method is particularly valued for its speed and simplicity, making it suitable for routine quality control during fuel production and distribution.
