Purchase of an Inductively Coupled Plasma-Atomic Emission Spectrometer

这份来自化学研究仪器项目的合同将帮助西肯塔基大学化学系获得一台电感耦合等离子体原子发射光谱仪（ICP-AES）。该仪器将用于以下领域的研究调查：燃料中微量元素的分析，枪弹残留物的分析，泥浆固体中元素的直接测定，法医土壤分析，定植草中元素的分析，树木年轮中元素的分析，以及动物血液和粪便样本的元素分析。原子发射光谱法对样品进行直接的元素分析。通过对样品进行热汽化，然后在惰性载气中输运到等离子体中，将固体雾化到电感耦合等离子体（ICP）中，引起了很大的兴趣。元素的ICP激发原子发射线允许对样品中存在的元素进行定性鉴定。ICP-AES最常用于实时过程控制、环境监测和电子级材料制造等领域的多元素分析。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Western Kentucky University acquire an Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES). The instrument will be used in research investigations in the following areas: analysis of trace elements in fuels, analysis of gunshot residues, direct determination of elements in slurried solids, forensic soil analysis, analysis of elements in colonizing grasses, analysis of elements in tree growth rings, and elemental analysis of animal blood and excrement samples. Atomic emission spectrometry gives the direct elemental analysis of samples. Much interest has been directed toward the atomization of solids into the inductively coupled plasmas (ICP), by thermal vaporization of the sample followed by transport into the plasma in an inert carrier gas. ICP excited atomic emission lines of the elements allow for qualitative identification of the elements present in the sample. ICP-AES is most frequently used for multi element analysis in areas such as real-time process control, environmental monitoring, and electronic-grade materials manufacturing.
