Abstract:
Middle distillates like jet fuel and diesel have strict requirements regarding aromatic content to reduce pollution and maximize engine life. The current referee method, ASTM D1319, is becoming unsustainable as remaining dye stocks wane. Current alternative methods include supercritical fluid chromatography (SFC) and high-performance liquid chromatography (HPLC). Vacuum ultraviolet (VUV) spectroscopy is a relatively new GC detection methodology that can analyze jet fuel in less than 14 minutes and diesel in less than 20 minutes. Automated quantitation using time interval deconvolution (TID) can determine total mono- and di-aromatics for jet fuel and total mono-, di-, tri-, and tetra-aromatics for diesel.
