The instrument allows the measurements of 1.) the concentrations as well as of the speciation of elements (e.g. arsenic, selenium, vanadium, mercury) 2.) trace elements (including rare earth elements) with very low detection limits and 3.) particle size distributions and the particle metal content. Those measurements will be carried out on real environmental samples (soil, water, plants, sediments, particles, organisms) as well as on samples collected during various experiments and will thus allow a considerable scientific progress in environmental science.Such an instrument is currently not available at the entire BUW. This is the reason why the planned scientific studies cannot be performed on-site until now. The instrument will be used by several teams belonging to various faculties as well as by international collaborators. The required human resources, the analytical expertise as well as the technical infrastructure are available. Prof Rinklebe (use percentage 65%) will use the instrument to elucidate the processes of mobilization and formation of speciation of trace elements in frequently flooded soil under dynamic redox conditions. The planned research activities will significantly enhance our basic understanding about the biogeochemical behavior and cycles of trace elements in the environment. Since several of those elements are toxic for humans and the living environment the associated risks can be better assessed, evaluated and finally forecasted. Prof Bornhorst (use percentage 20%) will use the instrument 1.) to quantify the total metal content in biological matrices, which is important for the interpretation of molecular biological data, and 2.) to perform the speciation analysis using LC-ICP-MS/MS, which will provide information about metabolic processes (toxification / detoxification). The measurements of elements in single cells and nematodes allow getting deeper insights into the individual biological variability. Prof Benter and Dr Kersten (use percentage 15%) plan to use the instrument 1.) for detecting metal aerosols in micro-spark-discharges, 2.) for developing selective ionic-molecular-reactions in double reaction direction and 3.) for plasma-spectroscopy as they depend on diverse operating conditions such as the charge of samples. The last two issues are closely related to the works of the teams of Prof`s Rinklebe and Bornhorst.

该仪器允许测量1。）元素（如砷、硒、钒、汞）的浓度和形态2.）微量元素（包括稀土元素）具有非常低的检测限和3.）粒度分布和颗粒金属含量。这些测量将对真实的环境样品（土壤、水、植物、沉积物、颗粒、有机体）以及在各种实验中收集的样品进行，因此将使环境科学取得相当大的科学进展。这就是为什么计划中的科学研究到现在还不能在现场进行的原因。该仪器将由属于不同院系的几个小组以及国际合作者使用。具备所需的人力资源、分析专门知识以及技术基础设施。Rinklebe教授（使用率65%）将使用该仪器阐明在动态氧化还原条件下经常被淹土壤中微量元素的动员和形成过程。计划中的研究活动将大大提高我们对环境中微量元素的地球化学行为和循环的基本认识。由于其中几种元素对人类和生活环境有毒，因此可以更好地评估、评价和最后预测相关风险。Bornhorst教授（使用百分比20%）将使用仪器1。）量化生物基质中的总金属含量，这对于分子生物学数据的解释很重要，以及2.）使用LC-ICP-MS/MS进行形态分析，这将提供有关代谢过程（净化/解毒）的信息。单细胞和线虫中元素的测量可以更深入地了解个体生物学变异性。Benter教授和Kersten博士（使用百分比15%）计划使用仪器1。）用于检测微火花放电中的金属气溶胶，2.）用于在双反应方向上发展选择性离子-分子-反应和3.）因为它们取决于不同的操作条件，如样品的电荷。最后两个问题与Rinklebe和Bornhorst教授团队的工作密切相关。
