    Abstract: Carbonyl compounds, such as ketones, aldehydes, esters, amides, anhydrides and carboxylic acids are added to a material, particularly a liquid material as markers. Subsequently the carbonyl compound(s) are identified by measuring the absorbency peak(s) of the carbonyl compounds in the mid-IR range. Carbonyl compounds soluble in non-polar solvents and substantially insoluble in water are particularly suitable for tagging and identifying petroleum fuels. For use in petroleum fuels, the carbonyl compound(s) preferably contains no element other than carbon, hydrogen, oxygen and nitrogen. Digital carbonyl marker systems, i.e., systems containing two or more carbonyl compounds in predetermined ratios, can be determined quantitatively with instruments, such as SpecTrace.TM. which measure absorbance in the mid-IR region.
