Multiphoton ionization (MPI) using ultraviolet laser light has emerged as a promising new technique in mass spectrometry. It is a highly efficient soft ionization method which at higher laser powers is capable of inducing extensive fragmentation analogous to electron ionization. The GC/MPI-FTMS has been shown to provide the selectivity, sensitivity and resolution predicted for the method. The future of this technique possibly lies in the sensitive and highly specific detection of target compounds by high resolution single or multiple-ion-monitoring, such as is required for trace analysis of environmental contaminants.
