Abstract:
D7566 specifies the properties of selected hydrocarbon types (paraffins, cycloparaffins, and aromatics) for renewable aviation fuels to be measured by ASTM D2425. D2425-19 is an analytical technique using mass spectrometry (MS). The separation is not well-defined and has proven difficult. D8305 is accepted in D7566 for the measurement of aromatic hydrocarbons in aviation turbine fuels. A simple modification can be made to D8305 to split the flow eluting from the column to the FID, for the mass percent and the MS for the mass spectrum used in the calculations for D2425. The SFC-FID-MS will be discussed for D2425.
