Abstract:
ASTM D3606 (benzene), ASTM D5599 (ethanol, oxygenates), and ASTM D5769 (benzene, toluene, total aromatics) gasoline tests typically require three dedicated GC systems, all using helium carrier gas, which is in short supply. ASTM D8071-17, PIONA and oxygenates analysis with gas chromatography – vacuum ultraviolet spectroscopy (GC-VUV), allows benzene, toluene, total aromatics, and ethanol, as well as other parameters, to be accomplished on one GC in less than 35 min.
Helium use can be eliminated entirely by employing alternate GC carrier gases, such as hydrogen and nitrogen. This presentation will demonstrate how using GC-VUV for the analysis of gasoline-range samples.
