• Formation behaviors of negative thermal ions from a mixed solution of platinum group elements (PGEs; Ru, Rh, Pd, Os, Ir and Pt), Mo, W, Re and Au has been explored using two thermal ionization mass spectrometers. The dominant negative thermal ions were RuO^-_3,OsO^-_3,IrO^-_2,PtO^-/Pt^-, MoO^-_3,ReO^-_4 and Au^- using a Pt single filament method. The ion beam intensities were ReO^-_4>OsO^-_3>IrO^-_2≈RuO^-_3>MoO^-_3. Negative ions of halogens, Cl^-, Br^- and I^-, were also observed. No negative ion species for Rh, Pd and W were, however, detected in this study. The ion currents of thermal negative ion species were reduced when one or two very strong negative ions such as Cl^-, Br^- or ReO^-_4 were coexisting. Overnight baking at a low filament temperature could reduce this effect.
