 A series of fluorescent dyes, prototypes of markers for hidden and visual protection of fuel, has been developed and the promise of their practical use has been shown. It has been established that the limits for determinations of fluorescent markers in fuel are 2.5–200 mg/m3, which is two to three orders of magnitude lower than the concentrations of dyes used for visual marking (for example, 6 g/m3 for the “Euromarker” dye). The stability of fluorescent marker solutions is sufficient for their practical application. Based on marker M-560, a demo sample of the fuel marker was created and it was shown that determination using this marker can be carried out even in the presence of visual markers, such as, Solvent Red 24. It has been shown that the lower thresholds for determining the markers M-560 and M-640 by their fluorescent signals are no more than 10–6 mol/L and 10–7 mol/L, respectively. The following laboratory procedures have been developed: the obtaining of the fuel markers in the form of concentrated solutions; the use and detection of the marker M-560 in fuel; the use and detection of the marker M-640 in fuel; the use and detection of the fluorescent marker M-560 in fuel which is mixed with the non-fluorescent Solvent Red 24 dye.
