A new separation scheme based on an inexpensive equipment is developed to identify the major chemical types in aviation hydro carbon fuels. This equipment can be called as a centrifugal, high performance, radial, preparative, gradient developed, thin-layer chromatography. The best available, state-of-the-art separation schemes will be used for comparison. Verification will be carried out either by internal standards OR by capillary, high resolution, gas chromatography-mass spectrometry analysis.
