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

凭借化学研究仪器和设施（CRIF）计划的这一奖项，弗吉尼亚联邦大学化学系将获得电喷雾电离四极杆飞行时间质谱仪。这一设备将加强若干领域的研究，包括：（a）细胞色素c、细胞色素c氧化酶和分子氧之间的电子转移反应;（B）复杂系统中化学动力学的特性;（c）用于依赖氧和过氧化物的氧化作用的仿生载体催化剂;（d）用于环境污染物痕量分析的抗体传感器的评估;（e）作为发光生物标记物的镧系元素（三）大环络合物;和f）氧化过氧化物酶的共振拉曼。 质谱（MS）是一种用于探测紧密结构细节并获得大量有机、生物有机和有机金属分子的分子组成的技术。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.
