ABSTRACT:
A liquid hydrocarbon fuel composition comprises at least one tagging agent and a mixture of hydrocarbon components having boiling points in the range of about 100 degrees F. to about 800 degrees F. The tagging agent is present at a concentration in the range of from about 0.5 ppb to about 500 ppb. The tagging agent is elutable by chromatographic analysis of the liquid hydrocarbon fuel composition apart from the hydrocarbon components of the fuel composition. The tagging agent is formed from an organic compound containing elements found at natural isotopic abundance. Preferably, two or more tagging agents are employed in the fuel so that each fuel composition can be assigned a unique tagging agent composition. Analysis techniques are also disclosed.
