Acquisition of an Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometer for Research and Education

在化学研究仪器和设施计划(CRIF)的这一奖项下，弗吉尼亚联邦大学化学系将获得一台电喷雾电离四极杆飞行时间质谱仪。该设备将加强一些领域的研究，包括a)细胞色素c、细胞色素c氧化酶和二氧化氧之间的电子转移反应；b)复杂体系中化学动力学的表征；c)氧和过氧化氢依赖氧化的仿生载体催化剂；d)用于环境污染物痕量分析的基于抗体的传感器的评估；e)稀土(III)大环配合物作为发光生物标记；以及f)氧化过氧化物酶的共振拉曼光谱。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生物化学在内的许多领域产生影响。

With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Virginia Commonwealth University will acquire an Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometer. This equipment will enhance research in a number of areas including a) electron transfer reactions between cytochrome c, cytochrome c oxidase and dioxygen; b) characterization of chemical dynamics in complex systems; c) biomimetic-supported catalysts for oxygen- and peroxide-dependent oxidations; d) assessment of antibody-based sensors for trace analysis of environmental contaminants; e) lanthanide(III) macrocyclic complexes as luminescent bio-markers; and f) resonance Raman of oxidized peroxidases. 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 biochemistry.
