| Outline of Final Research Achievements |
Terrorist attacks are occurring frequently in various countries around the world, and it needs to develop a technique to suppress this undesirable events. If the substances used in the terrorist attacks can be identified by the scientific analysis of the residues, it will prevent new terrorism in the future. A variety of techniques have been developed for this purpose. However, there are problems in terms of sensitivity and selectivity. Laser ionization mass spectrometry is useful to selectively ionize a target substance by optimizing the wavelength, suppressing dissociation of a molecule. We developed a mass spectrometer using a femtosecond Yb laser as an ionization source for practical trace analysis.
