The instrument (Jeol GC-MateII) is a used magnetic sector instrument equipped with EI (electron ionization) and FAB (fast atom bombardment) ionization. FAB is a mild ionization technique suitable for more polar compounds than electron ionization. FAB-MS can only be conducted by direct infusion. It has a mass spectrometric resolution of approximately 5000 (FWHM) giving a mass accuracy below 2 mDa, valuable in characterization applications as well as for confirmation of identity.
The instrument is mainly used for research in analytical, inorganic and organic chemistry and metabolomic studies in medicine.
