Consideration of coumarin analysis in gasoline by GC-MS using high efficiency ion source

Abstract

Analysis of coumarin for discrimination of kerosene and diesel oil in gasoline was considered by using GC-MS with high efficiency ion source. The sample was prepared by mixing kerosene and regular gasoline or high-octane gasoline. 0.01 mg/L coumarin in gasoline was easily detected using this method without interference of gasoline matrix.
