Compositional data determined on inorganic materials by electron microprobe analysis (EPMA) underpins a considerable amount research in Earth/planetary sciences. Spots down to 2/1000mm may be analysed quantitatively for major elements and some trace elements with an accuracy of <1%, and digital composition maps of the elemental spatial distribution can be generated. Increasing downtime on the 14 year-old UTasmania microprobe, coupled with diverse new and exciting applications in ore deposit research, environmental geoscience and geochronology force us to seek funds to replace the existing EPMA facility, which has logged ~101,000 hours of use involving ~250 researchers, and produced more than 500 refereed papers.

利用电子探针（EPMA）测定无机材料的成分数据是地球/行星科学中大量研究的基础。可对小至2/1000 mm的点进行主量元素和某些微量元素的定量分析，准确度<1%，并可生成元素空间分布的数字组成图。14岁的塔斯马尼亚大学微探针的停机时间越来越长，再加上在矿石存款研究、环境地球科学和地质年代学方面各种新的令人兴奋的应用，迫使我们寻求资金来取代现有的EPMA设备，该设备已记录了约101，000小时的使用，涉及约250名研究人员，并产生了500多篇参考论文。
