Upgrade of an XRF Spectrometer

9311758莱利从化学研究仪器和设施计划的这一奖项将协助化学系在西肯塔基州大学在购买他们的x射线荧光光谱仪的升级。 这一升级将加强若干领域的研究，包括： 1. 垃圾衍生燃料与煤混烧残渣中主、次、痕量元素的测定。 2. 动物消化率研究中主要、次要和微量元素的分布。 3. 从元素组成预测灰的熔化温度和粘度。 4. 饲料中主要、次要和微量元素积累的分析。 % X射线荧光是一种用于固体和液体化学分析的非破坏性物理方法，其中样品被强烈的X射线束照射，所得X射线荧光光谱中的谱线与样品中由其谱线波长识别的元素相关，并且其浓度由谱线强度确定。 ***

9311758 Riley This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at Western Kentucky University in the purchase of an upgrade of their x-ray fluorescence spectrometer. This upgrade will enhance research in a number of areas including the following: 1. Determination of major, minor, and trace elements in the residues from co-firing refuse-derived fuels with coal. 2. Distribution of major, minor, and trace elements in animal digestibility studies. 3. Prediction of fusion temperatures and viscosities of ashes from their elemental composition. 4. Analysis of major, minor, and trace element accumulation in feed lots. %%% The x-ray fluorescence is a non-destructive physical method used for chemical analysis of solids and liquids, where the sample is irradiated by an intense x-ray beam and the lines in the spectrum of the resulting x-ray fluorescence are related to the elements in the sample identified by the wavelength of their spectral lines, and their concentrations are determined by the intensities of the lines. ***
