Plasma emission spectrometry is a rapid and accurate method of chemical analysis for rocks and minerals which typically contain many elements in major, minor, and trace concentrations. The Department of Earth and Space Sciences at UCLA requests 50% of the cost of acquiring a plasma emission spectrometer system to replace their 23 year old X-ray fluorescence spectrometer that has been used for multielement chemical analysis in their departmental research programs. Ongoing research at UCLA requiring such analytical capabilities include field and laboratory interpretations of high-pressure metamorphic terranes and associated igneous rocks, lab studies of rocks derived from the earth's mantle, comparative geological and geochemical studies of vein-type and replacement-type ore deposits, large- scaled interpretations of mantle geochemistry and sedimentary basins, and cosmochemistry based on direct analysis of meteorites and lunar samples. Acquisition of the plasma emission spectrometer will allow a large user-base of geoscientists to carry out the necessary chemical analyses of a wide variety of geological samples.

等离子体发射光谱法是一种快速、准确的化学分析方法，用于对岩石和矿物进行化学分析，这些岩石和矿物通常含有多种主要、次要和痕量浓度的元素。 加州大学洛杉矶分校地球与空间科学系要求 50% 的成本购买等离子体发射光谱仪系统，以替换其已有 23 年历史的 X 射线荧光光谱仪，该光谱仪已在该系的研究项目中用于多元素化学分析。加州大学洛杉矶分校正在进行的需要这种分析能力的研究包括高压变质地体和相关火成岩的现场和实验室解释、地幔岩石的实验室研究、脉型和交代型矿床的比较地质和地球化学研究、地幔地球化学和沉积盆地的大规模解释以及基于直接理论的宇宙化学研究。 陨石和月球样本的分析。购买等离子体发射光谱仪将使大量地球科学家用户能够对各种地质样品进行必要的化学分析。
