A compact resonance ionization mass spectrometer is presented. It is presently applied for sensitive and highly selective ultratrace detemination of the long-lived radioisotope 41Ca for environmental, biological, and fundamental investigations. The development of coherent multistep resonance ionization enables the realization of experimental detection limits as low as 6 10 atoms per sample and very high isotopic selectivity above 12 10.
