The precision of isotope ratio analyses by ICP-SFMS is under optimal conditions better than 0.05% relative standard deviation.

This is not as good as for MC-ICP-MS, but still sufficient to separate lead from different sources, e.g.

in toxicological investigations, by the natural variation in isotope composition Tracers are used primarily in biological and medical research.

Here stable isotopes are an attractive alternative to radioactive isotopes since they carry no risk of radiation.

Isotope dilution is a sophisticated method for quantitative analysis of elements.

After "spiking" the sample with a stable enriched isotope of an element, the original concentration of that element can be calculated from the measured change in one or more isotope ratios.

Isotopes are atoms of a specific element that have different masses.

In nature, most elements occur as a mixture of several so-called stable isotopes in more or less constant proportions.
