多接收器电感耦合等离子体质谱的新应用

无机地球化学研究的进展通常依赖于新的技术开发。电感耦合等离子体质谱（ICP—MS）技术可以进行高精度的同位素比值分析，使以前很难测定的元素的分析成为可能。牛津大学地球科学系已经越来越多地开展多接收器电感耦合等离子体质谱分析，着重于解决从宇宙至环境化学领域的诸多问题。目前主要研究Cr同位素，确定Cr对Jurassic—Triassic边界可能产生的影响事件，以及采用铀系列同位素进行海洋学研究。

New Application of Multiple Collector ICPMS

Advances in Inorganic Geochemistry have often been dependant on introduction of new technology. The development of Inductively Coupled Plasma Mass Spectrometry (ICPMS) has allowed high-precision isotopic analysis of elements previously very difficult to analyse. In Oxford we have invested heavily in Multiple Collector Plasma Mass Spectrometry to address problems ranging from Cosmic to Environmental Chemistry. Examples of current projects being pursued are an investigation of Cr-isotopes to identify a possible impact event at the Jurassic-Triassic boundary, and the use of U-series isotopes in Oceanography.
