ResumoA High-performance liquid chromatography method utilizing a bonded aminosilane stationary phase, n-heptane mobile phase and refractive index detection is described for quantification of the compound class composition (saturates, single-ring aromatics, double-ring aromatics, polynuclear aromatics and polars) of olefin free kerosine and diesel fuels. Refractive index response factors for each of the compound classes have been determined using fractions obtained from preparative scale column chromatographic separation for a range of fuel samples. Variations in response factors for fractions derving from different fuel sources are described and are considered sufficiently small to allow acceptable analytical accuracy for refractive index detection.
