Education and training
Ultratrace Analysiswith Laser Radiation
Ultratrace analysis with RIMS
Principal of the resonance laser ionization mass spectrometry (RIMS):
1. Production of an atomic beam
2. Efficient three step ionization of the atoms by lasers
3. Mass separation of the ions by a time-of-flight mass spectrometer
4. Extremely high isotopic selectivity of 5×1012 and low experimental limit of detection of 106 atoms per sample
•Plutonium in the environment– Powder sample from the Elbmarsch– Water sample from the North Sea and the Irish Sea– Incorporation measurements – Stolen plutonium from a reprocessing facility– Uranium amunitions from the Kosovo– Water samples from Rheinland-Pfalz
•Calcium-41 in the biological medicine
•Uranium-236 in the environment
Applications of ultratrace analysis with RIMS
Application of synchrotron radiation for structural analysis
Investigation of long-lived radio-nuclides (actinides) in
– aqueous solutions,– soils,– plants and– microorganisms
