Fast atom bombardment ionisation is combined with charge stripping (CS) to produce bare and ligated metal dications. Abundant quantities of ions resulting from the bombardment of transition and lanthanide metal salts are produced and charge stripped. Qmin values obtained from the CS spectra agree within ± 0.5 eV of the respective second ionisation energies for the bare metal ions. Effects of ligands such as Cl and OH are observed as an increase in Qmin values relative to the bare metals ions, e.g. ΔQmin = 0.9 eV for CoCl+ and ΔQmin = 3.2 eV for HoCl+.
