The most important aspect of ICP-MS is its multielement capability which can be used for ultra-trace determination of elements in any matrix. The,highest accuracy was achieved only when ICP-MS was used as a definitive method in combination with isotope,dilution techniques, a method which was strongly promoted and supported by our friend Klaus G. Heumann.,It can be expected that his pioneering work related to,species-specific and species-unspecific isotope dilution,analysis [1–5] will form one important aspect in future ICP-MS applications in quantitative life sciences.
