Analysis of geological materials using inductively coupled plasma-mass spectrometry (ICP-MS)

我研究的长期目标是最大限度地发展电感耦合等离子体质谱（ICP-MS）分析地质样品的能力。重点是来自地圈的固体物质，但也包括来自水圈、大气和生物圈的样品，这些样品反映了它们与固体地球的联系，因此含有反映环境的微量元素。ICP-MS与其他重要的地理分析方法，特别是热电离质谱（TI-MS）和x射线荧光（XRF）的整合将继续发展成本效益高，精确和准确的分析目标。“没有任何方法是万灵药”是我工作的指导原则。我的长期目标是找到一种方法来测定元素周期表中所有自然存在的元素在真实样品中的浓度。纪念大学目前使用的ICP-MS和XRF程序接近这一目标，但还需要对分析物进行额外的工作。

The continuing long term goal of my research is to develop to the utmost, the capabilities of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) for the analysis of geological samples. The emphasis is on solid materials from the geosphere, but samples from the hydrosphere, atmosphere, and biosphere, which reflect their association with the solid earth and thus contain trace elements which reflect the environment, are included. The integration of ICP-MS with other important geoanalytical methods including especially thermal ionization-mass spectrometry (TI-MS) and X-ray fluorescence (XRF) will continue with the goal of developing cost effective, precise, and accurate analyses. That "no method is a panacea" is a guiding principle of my work. My long term goal is to develop methods to determine all of the naturally occurring elements of the periodic table at the concentrations that they are found in real samples. ICP-MS along with XRF procedures currently in place at Memorial University approach this goal, but there are analytes for which additional work is required.
