Abstract:
Analysis of benzene, toluene, and aromatics in gasoline by ASTM D5769 using GC/MS ensures regulatory compliance and fuel quality. Recent costs associated with the use of helium carrier gas have left many laboratories exploring alternatives, such as hydrogen. In this poster, we compare results of ASTM D5769 analysis of gasoline using helium and hydrogen carrier gases. Area counts and repeatability for all compounds were similar for both carrier gases. Run times using H2 were ~22 minutes, whereas those for He were ~32 minutes. This improves sample throughput and reduces costs of operation.
