Abstract
A hydrocarbon liquid identification and tracing system based on fluorescence, high pressure liquid chromatography or thin layer chromatography and N-substituted or N,N'-dialkyl-4-amino-1,8-naphthalimides as the fluorophores is described. The liquid fuel tracing system based on the above naphthalimides is based on the 2.sup.n -1 binomial system and provides inexpensive and extremely accurate and sensitive monitoring and source identification.
