Differentiation of commercial fuels based on polar components using negative electrospray ionization/mass spectrometry Differentiation of commercial fuels based on polar components using negative electrospray ionization/mass spectrometry

Polar components in fuels may enable differentiation between fuel types or commercial fuel sources. A range of commercial fuels from numerous sources were analyzed by flow injection analysis/electrospray ionization/mass spectrometry without extensive sample preparation, separation, or chromatography. This technique enabled screening for unique polar components at parts per million levels...
