Study on Sulfur Compounds in the Gasoline

摘要

A procedure to quantify volatile, organic sulfur compounds in gasoline was developed using solid-phase microextraction to preconcentrate the analyses followed by GC and detection with a sulfur chemiluminescence detector (SCD). The effects of temperature, time and PDMS fibers types on the extraction of gasoline has been investigated. The results show that a range of sulfur compounds were identified in gasoline. 75um PDMS, 30min, and 50°C were the optimum extraction conditions. Using the developed method can be used to identify gasoline residues in the fire.
