Aquisition of a multi-source reflectron time-of-flight mass spectrometer

北卡罗来纳农工大学物理系将从主要研究仪器(MRI)计划获得这一奖项，从而获得一台多源反射式飞行时间质谱仪。该设备将加强若干领域的研究，包括：a)含金属纳米团簇的合成、结构和性质；b)质量选择分子离子和团簇离子的毫米波光谱；c)利用质量测定合成、分离和表征产生黑素的底物和辅因子；以及d)开发去污有机污染物，特别是农药的电化学技术。质谱仪(MS)是一种用于探测大量有机、生物有机和有机金属分子的内部结构细节和获得其分子组成的技术。这些研究的结果将对包括环境化学和纳米科学在内的许多领域产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Physics at North Carolina A&T University will acquire a multi-source reflectron time-of-flight mass spectrometer. This equipment will enhance research in a number of areas including a) the synthesis, structure and properties of metal-containing nanoclusters; b) millimeter-wave spectroscopy of mass-selected molecular ions and cluster ions; c) the synthesis, isolation and characterization of melanogenic substrates and cofactors using mass determination; and d) development of electrochemical techniques in the decontamination of organic contaminants, especially pesticides. Mass spectrometry (MS) is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic, and organometallic molecules. The results from these studies will have an impact in a number of areas including environmental chemistry and nanosciences.
