Abstract
A method of fuel analysis comprising subjecting a fuel sample comprising a fuel marker and a fuel matrix to fluorescence spectroscopy to generate a measured emission spectrum comprising a first spectral component (type and amount of marker in sample), a second spectral component (spectral perturbation), and a third spectral component (matrix fluorescence); deconvoluting the measured emission spectrum to yield a deconvoluted measured emission spectrum (first and second spectral components) via removal of third spectral component; decoupling the deconvoluted measured emission spectrum to yield a corrected emission spectrum (first spectral component) via a projection function which orthogonally projects the deconvoluted measured emission spectrum onto a subspace devoid of the second spectral component; and determining the amount of fuel marker in the fuel sample from the corrected emission spectrum. The method of fuel analysis comprises temperature corrections.
