Acquisition of a High-Performance Two-Sector Mass Spectrometer for Research in Chemistry and Material Sciences

9871451卡尔塔索夫高分辨率磁扇形质谱计将根据这一重大研究仪器奖购买。该仪器包括一台高分辨率、高传输效率、高m/z范围的双聚焦质谱仪。该质谱仪配备了标准的电子碰撞/化学电离离子源，以及易于互换的快速原子轰击、电喷雾电离和场解吸/电离源。该配置还包括两个碰撞单元和提供串联能力的链接扫描单元。该仪器的主要用户包括来自聚合物科学系和化学系的小组。该仪器还将使来自其他系的一大批小用户受益，如生物化学和分子生物学、兽医和动物科学、化学工程系、食品科学系。来自阿默斯特学院和芒特山的研究人员也将使用它。霍利奥克学院。将使用质谱仪的16个研究小组包括22名博士后研究员、82名研究生和33名本科生。用重大研究仪器奖购买的高分辨率磁扇形质谱仪将成为马萨诸塞大学质谱学中心的一部分。由于其高分辨率、无与伦比的质量精度和多种电离模式，新仪器将极大地扩展该中心提供的分析能力。*

9871451KaltashovA high resolution magnetic sector mass spectrometer will be purchased under this Major Research Instrumentation award. The instrument includes a high-resolution, high-transmission efficiency, and high m/z range double focusing mass analyzer. The mass spectrometer is equipped with a standard electron impact/chemical ionization ion source, as well as easily interchangeable fast atom bombardment, electrospray ionization and field desorption/ionization sources. The configuration also includes two collision cells and a linked scan unit providing tandem capabilities. Major users of the instrument include groups from the Department of Polymer Science and the Department of Chemistry. The instrument will also benefit a large group of minor users from other departments such as Biochemistry and Molecular Biology, Veterinary and Animal Science, Department of Chemical Engineering, Food Science. It will also be used by researchers from Amherst College and Mt. Holyoke College. The 16 research groups that will be users of the mass spectrometer include 22 post-doctoral fellows, 82 graduate students and 33 undergraduate students.%%%The high resolution magnetic sector mass spectrometer purchased with the Major Research Instrumentation award will become a part of the University of Massachusetts' Mass Spectrometry Center. Because of its high resolution, unmatched mass accuracy and a variety of ionization modes, the new instrument will greatly expand the analytical capabilities offered by the Center.***
