With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry and Biochemistry at Northern Illinois University will acquire a liquid chromatograph - ion trap mass spectrometer. This equipment will enhance research in a number of areas including a) characterization of heme protein samples; b) photochemical studies of autofluorescent pigments; c) development of new analytical tools based on protein-ligand interactions; d) studies of carboranes and metallacarboranes; e) investigations of reaction rates and thermodynamics for ions in the gas phase; and f) the development of reusable ruthenium carbene catalysts for olefin metathesis. Liquid chromatography with mass spectrometric detection (LC-MS) is an extremely powerful technique used for the separation and analysis of complex mixtures. This instrument will substantially strengthen scientific research in a wide variety of projects, ranging from the measurement of physical properties of ions to biochemical structural analysis.

在化学研究仪器和设施(CRIF)计划的这一奖项下，北伊利诺伊大学的化学和生物化学系将获得一台液体色谱仪-离子陷阱质谱仪。该设备将加强若干领域的研究，包括a)血红素蛋白样品的表征；b)自发荧光颜料的光化学研究；c)基于蛋白质-配体相互作用的新分析工具的开发；d)碳硼烷和金属碳硼烷的研究；e)气相离子的反应速率和热力学的研究；以及f)可重复使用的烯烃歧化反应催化剂的开发。液-质联用(LC-MS)是一种用于复杂混合物的分离和分析的非常强大的技术。该仪器将大大加强各种项目的科学研究，从测量离子的物理性质到生物化学结构分析。
