Abstract
A method for tagging an oil so that subsequently it may be identified as to source by incorporating into the oil as a tracer material a minor amount of certain halohydrocarbons or halocarbons, utilizing the so-tagged oil in any desired manner wherein control of the oil is at least temporarily lost, and thereafter analyzing an oil suspected to contain at least a portion of the so-tagged oil for the presence of the tracer material by gas chromatography, using a pulsed election capture detector.
