Molecular formula determination of constituents in Arabian mix vacuum residue by electrospray ionization fourier transform ion cyclotron resonance mass spectrometry
Fourier transform ion cyclotron resonance mass spectrometry equipped with electrospray ionization (ESI FT ICR MS) was successfully applied to determine molecular formulas of components in Arabian mix vacuum residue (AM-VR) by measurement of highly accurate m/z values of molecular ions and analysis of spectral pattern without any pre-separation procedures.
