Abstract
The present disclosure provides methods for identifying a hydrocarbon fuel, such as the presence and/or amounts of marker compounds having a fluorescence intensity and, through correlation, the presence and/or amounts of additive package(s) within the hydrocarbon fuel. The methods include obtaining a sample of a hydrocarbon fuel including a marker compound having fluorescence, combining the hydrocarbon fuel with water, and subjecting a water phase thereof to light for observing fluorescence.
