Analysis of Middle Distillate Fuels by High Resolution Field Ionization Mass Spectrometry.

Abstract

We have developed an analytical method for the rapid and detailed chemical characterization of distillate fuels using high-resolution field ionization mass spectrometry (HR-FIMS). Field ionization produces only the molecular ions for most compounds and is therefore particularly useful for the analysis. A vintage AEI MS-9 mass spectrometer was refurbished and modified to house an SRI volcano-style field ionizer. By operating the mass spectrometer at a resolving power of 3000, all the hydrocarbon z-series present in the fuel can be resolved. Software was written for sorting the peaks according to their z-series, applying the appropriate response factors, printing and plotting the reports, and averaging replicate analyses. Keywords: Distillate, Fuel, Analysis, Jet fuel, Diesel fuel, Mass spectrometry, Field ionization, High resolution series.
