Abstract: | The applications of inductively coupled plasma -mass spectrometry (ICP-MS) to geoanalysis are reviewed. This technique offers the ability to determine elemental abundances and isotope ratios; it has proven to be sensitive, precise and accurate, and represents a significant advance in instrumentation suitable for rock analysis. This review deals principally with the application of ICP-MS to elemental analysis. Literature citations are complete as of December 31, 1987; particular attention has been paid to data reported for certified reference materials. Although most current ICP-MS analysis employs conventional nebulization of solution samples, there is considerable effort being made to develop viable alternative sample introduction schemes that can be applied to rock analysis. The lack of adequately defined certified reference rock materials is apparent for ICP-MS and other techniques that are capable of routine determinations in the ng/g (ppb) range. |
