Application of mass spectrometry for the identification of chemical species in gas phase chemistry

We have studied the gas phase chemistry for transactinide elements by use of dipivaloylmethane (dpm) complex of fission products from 252Cf. However, the chemical species of the generated volatile compounds ware not clear. In order to argue the chemical property, it is necessary to clarify chemical species of volatile compounds. For the identification of chemical species at the gas phase chemistry, mass spectrometry with laser ionization is considered to be suitable. The resonance enhanced multi-photon ionization (REMPI) by a tunable laser is used as an ionization method. (author)
