Sample Preparation for Isotopic Analysis on the Multicollector ICP-MS

Richard Wanty, Ian Ridley, Paul Lamothe, Ruth Wolf and David Borrok

The Minerals Program's new MC-ICP-MS represents an exciting tool capable of sensitive isotopic analyses of trace constituents in environmental samples. However, the great sensitivity of this instrument also necessitates that environmental samples be carefully prepared to separate the constituents of interest from the rest of the sample matrix. Our first efforts are directed at separating Cu, Fe, and Zn from each other and from the sample matrix.
