Abstract:
As the trend toward “greener,” renewable biofuels becomes more prevalent, concerns over pipeline cross-contamination and mixing are addressed through more rigorous analytical testing. For jet fuels, especially, regulated methods like IP585 and ASTM D7974 respectively address the accurate quantitation of fatty acid methyl esters (FAMEs), which impact jet fuel freezing points and can cause fuel gelling to occur, and determination of specific hydrocarbons in synthesized iso-paraffins (SIP) used for blending with jet fuel. Utilizing two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GCxGC-TOFMS), methods for determination of FAMEs and SIP hydrocarbons using a new diverting flow modulator have been developed.
