✦ Synopsis

Resonant laser mass spectrometry is a promising method for chemical trace analysis since it combines selectivity, sensitivity and rapidity of measurement. It is a two-dimensional technique incorporating medium-or highresolution UV spectroscopy and time-of-flight mass spectrometry. No sample preparation and chemical clean-up is necessary to reach detection limits in the sub-ppb range even when highly complicated mixtures of chemical species are analyzed. After an introduction to the principles of resonant laser mass spectrometry, illustrative examples of applications are presented. Drawbacks, possibilities of overcoming them, some interesting features and future developments of resonant laser mass spectrometry are discussed.

Strontium‐90 is one of the most poisonous radionuclides. Its toxicity results from its long half‐life of 28.5 years and permanent deposition in the blood‐forming bone system. Strontium‐90 is formed in high yields during the nuclear fission of uranium‐235 and plutonium‐239. The classic analytical pro
