Resonance ionization mass spectrometry has been explored in respect to its capabilities for isobaric suppression, isotopic selectivity, and overall efficiency. Theoretical calculations within the density matrix formalism on coherent multi-step excitation processes predict high specifications, which have been confirmed by spectroscopic measurements in Ca and which make the technique attractive for ultratrace detection. Analytical applications are found in the determination of the ultrarare isotope 41Ca for cosmochemical, radiodating, and medical applications.
