Abstract Information :
Fuels analysis is performed using a variety of methodologies, including GC-FID Detailed Hydrocarbon Analysis (DHA) and multidimensional GC for gasolines, and Fluorescent Indicator Adsorption (FIA) for jet fuels. However, these methods have several drawbacks, including long run times, complex configurations, and in the case of FIA, grave concerns over the availability and quality of the dye required to perform the analysis.
Gas chromatography - vacuum ultraviolet spectroscopy (VUV) is a relatively new analytical methodology that utilizes moleculesâ€™ unique spectral absorbance fingerprints in the vacuum ultraviolet wavelength range (125-240 nm) to identify and quantitate analytes. A single GC-VUV hardware configuration can perform PIONA-class quantitative analysis ' including speciation of conjugated dienes ' in gasoline samples, as well as measure total saturates, aromatics, and di-aromatics in jet fuel samples.
