Description
Resonance ionization mass spectrometry (RIMS) is a natural outgrowth of RIS. The result of an RIS process is an ion pair. The electron can be used to detect the process, and single atom detection has been demonstrated by this method. The cation resulting from the RIS process actually carries more easily accessible and useful information (i.e. the mass of the ion). RIMS is useful in mass analysis. The development of RIMS has proceeded along several different directions, using CW or pulsed lasers, narrow or wide band laser energies, different kinds of sample generation, and different kinds of mass separations. RIMS in various forms can be used to obtain either element or isotope selectivity. Even though the RIMS technique has developed along several lines, several things are common to all approaches. Ultimately RIMS requires gaseous, free, atoms. RIMS makes use of the photoionization of these atoms by absorption of photons through allowed transitions involving real energy levels. The ion once formed is detected by standard mass spectrometric techniques.
