Abstract:
1. A method for identifying blend ratios in an original target fuel blend using fluorescence, the method comprising steps of: (a) exposing the original target fuel blend to ultraviolet laser radiation to excite particles in the original target fuel blend and measuring a first fluorescence of the original target fuel blend to obtain a target spectrum; (b) placing a first fuel in a vessel; (c) adding a predetermined quantity of a second fuel to the first fuel to create a blend; (d) measuring a second fluorescence of the blend to produce a blend spectrum; (e) comparing the blend spectrum to the target spectrum; (f) repeating steps (c), (d), and (e) until the blend spectrum substantially matches the target spectrum; and (g) recording a cumulative quantity of the first fuel and a cumulative quantity of the second fuel present in the blend having the blend spectrum that substantially matches the target spectrum.
