Researchers have trained an e-nose, which detects chemicals in the air, to identify the origin of oil based on the proportion of volatile organic compounds. Since oil is a mixture of different hydrocarbons present in varying proportions depending on its source, the e-nose could be used to locate soil-contaminating oil spills, monitor the environment at refineries, and conduct oil field studies.Researchers have trained an e-nose, which detects chemicals in the air, to identify the origin of oil based on the proportion of volatile organic compounds.
