This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program, the Department of Chemistry at the University of Central Arkansas will acquire a liquid chromatography triple quadrupole mass spectrometer and a time-of-flight mass spectrometer for non-chromatographable materials and for in situ analysis. A variety of research projects will be investigated including: Reactivity, Spectroscopic, and Sensing Properties of Nickel Complexes on Solid Organic Supports; Photolabile Amino Acid Radical Precursors; Synthesis and Oxygen Transport Properties of Highly Fluorinated Dendrimers; Retinoid Metabolism in the Presence of Thiazolidinediones; Analysis of Lipids from Bacterial Growth Media and their Potential in Taxonomy; Laser Desorption Studies of Aromatic Nanofilms Adsorbed on Evaporated Metal Films and Metal Powders; and the Characterization of Organic Binders in Ancient Cave Paints.Mass spectrometry (MS) is an analytical technique used to identify the chemical composition of a sample and to determine its purity by measuring the mass of the molecular constituents in the sample. Liquid chromatography is a separation technique that precedes the mass spectrometry analysis. It separates a mixture into its several constituent chemicals which are then analyzed and identified by the mass spectrometer. Mass spectrometry is one of the most widely used analytical instrumentation techniques. Because of this, it is important for undergraduate students to be trained in the technique on modern instrumentation as they participate in research projects such as those mentioned above.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。通过重大研究仪器（MRI）计划的这一奖项，中央阿肯色州大学化学系将获得一台液相色谱三重四极杆质谱仪和一台飞行时间质谱仪，用于非色谱材料和原位分析。 将研究各种研究项目，包括：固体有机载体上镍络合物的反应性，光谱和传感特性;光不稳定氨基酸自由基前体;高氟树枝状聚合物的合成和氧传输特性;噻唑烷二酮存在下的维甲酸代谢;细菌生长培养基中脂质的分析及其在分类学中的潜力;蒸发金属薄膜和金属粉末上吸附芳香族纳米薄膜的激光解吸研究和古代洞穴涂料中有机粘合剂的表征。质谱（MS）是一种分析技术，用于鉴定样品的化学成分，并通过测量样品中分子成分的质量来确定其纯度。sample. 液相色谱是一种先于质谱分析的分离技术。 它将混合物分离成几种化学成分，然后由质谱仪进行分析和鉴定。 质谱是最广泛使用的分析仪器技术之一。正因为如此，它是重要的本科生在现代仪器技术的培训，因为他们参与的研究项目，如上述。
