With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of California in Riverside will acquire a Hybrid Quadrupole/Orthogonal Time-of-Flight Mass Spectrometer. This equipment will enhance research in a number of areas including a) regiochemistry of ring assembly; b) fragments from chemical cleavage of proteins; c) isotopic labeling of steroids and seco-steroids; d) particulate formation in smog chamber simulations; e) synthesis of heterofullerenes; and f) deuterium exchange on platinum surfaces. 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 materials chemistry, polymer processing and biology.

凭借化学研究仪器和设施（CRIF）计划的这一奖项，加州大学滨江分校化学系将获得混合四极杆/正交飞行时间质谱仪。该设备将加强若干领域的研究，包括a）环组装的区域化学; B）蛋白质化学裂解的碎片; c）类固醇和开环类固醇的同位素标记; d）烟雾室模拟中的微粒形成; e）杂富勒烯的合成; f）铂表面的氘交换。 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。这些研究的结果将在许多领域产生影响，包括材料化学，聚合物加工和生物学。
