Samples were collected by SAIC and submitted to ETC and analyzed by gas chromatography using a FID to determine the hydrocarbon composition. <br /> 2. See Appendix E.3 for the fuel-fingerprint analytical report. <br /> 3. Sample contains moderately weathered SJV crude. <br /> 4. Sample contains very low concentration of non-specific hydrocarbon in the extract. <br /> 5. Sample contains extremely weathered SJV crude. <br /> 6. Sample contained compounds that are indicative of gasoline,diesel fuel#2,and crude oil or bunker fuel. The chromatographic profile for the crude region <br /> of the chromatogram is typical of an SJV crude profile. <br /> 7. The sample contains a minute amount of hydrocarbon compounds;however,there were compounds detected that correspond to gasoline and middle distillate <br /> hydrocarbons.
