MRI: Acquisition of a High Resolution MALDI-TOF Mass Spectrometer for Chemical Research

在重大研究仪器(MRI)采购计划的支持下，杜兰大学化学系将获得一台基质辅助激光解吸电离飞行时间质谱仪(MALDI-TOF)。该光谱仪将用于各种领域的研究，包括聚合物大环的合成、酶聚合反应的表征、酶的机理研究、有机金属催化剂以及过渡金属络合物的多金属捕光系统。基质辅助激光解吸电离(MALDI)飞行时间(TOF)质谱仪是表征合成和天然大分子的首选技术。它可以准确地测定大分子的相对分子质量并推断其结构。该仪器将致力于服务杜兰大学的学生，以及邻近的洛约拉、泽维尔和迪拉德大学。它将用于各种教育和服务活动，包括对学生进行仪器分析和生物化学课程的教育。

With support from the Major Research Instrumentation (MRI) Acquisition Program, the Department of Chemistry at Tulane University will acquire a Matrix-assisted Laser Desorption Ionization Time of Flight Mass Spectrometer (MALDI-TOF). The spectrometer will be used to investigate a variety of areas including synthesis of polymer macrocycles, characterization of enzymatic polymerizations, mechanistic studies of enzymes, organometallic catalysts, and polymetallic light harvesting ensembles of transition metal complexes. Matrix assisted laser desorption ionization (MALDI) time of flight (TOF) mass spectrometry is the technique of choice for characterization of synthetic and natural macromolecules. It allows molecular weights of large molecules to be determined accurately and structures to be deduced. The instrument will be dedicated to serving Tulane students, and neighboring Loyola, Xavier and Dillard universities. It will be used in a variety of education and service activities including the education of students in instrumental analysis and biochemistry courses.
