Detection of adulteration in the petroleum fuels (gasoline and diesel) is challenging because
the adulterants usually include those compounds which are already present in these fuels …

The desorption and ionization of analytes directly from surfaces or natural matrices under
ambient conditions has greatly simplified chemical analysis by mass spectrometry. Among …
