Selective laser ionization for mass-spectral isotopic analysis
Abstract
Resonant enhancement of the ionization process can provide a high degree of interference problem. In addition, extension of this method to isotopically selective ionization has the potential for greatly increasing the range of isotope ratios that can be determined experimentally. This gain can be realized by reducing or eliminating the tailing of the signal from the high-abundance isotope into that of the low-abundance isotope, augmenting the dispersion of the mass spectrometer. The hardware and techniques used in both the pulsed and cw RIMS experiments are discussed. Results are presented for both cw ionization experiments on Lu/Yb mixtures, and spectroscopic studies of multicolor RIMS of Tc.
