Fuel Chromatogram

The Gas Chromatograph (GC) coupled with a Flame Ionization Detector (FID) will detect petroleum hydrocarbons found in fuels. Different chromatographic results are generated by different fuel substances, each with characteristic patterns indicative of the type of fuel being analyzed. Comparison of chromatograms is useful in identifying and comparing fuels, and is also very effective in tracing fuel leak sources. Below are examples of chromatograms for commonly used fuels.

Diesel

Jet Fuel

Gasoline
