Acquisition of a MALDI Ion Trap Mass Spectrometer

在主要研究仪器（MRI）项目的支持下，纽约城市大学化学系将获得一台矩阵辅助激光解吸电离飞行时间（MALDI-TOF）质谱仪。该仪器将用于各种各样的研究项目，包括对a)卟啉材料的研究；B)植物转录因子；C)农业低聚物；D)多金属氧酸盐形成；e)蛋白质磷酸化。基质辅助激光解吸电离（MALDI）飞行时间（TOF）质谱法是获得非常大分子精确分子量的首选技术，具有极高的灵敏度。因此，使用MALDI-TOF质谱仪已成为一种标准技术，特别是在涉及生物分子的研究中。这项研究将在许多领域产生重大影响，特别是材料科学和生物化学

With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the City University of New York will acquire a Matrix-assisted Laser Desorption Ionization - Time of Flight (MALDI-TOF) Mass Spectrometer. This instrument will be used in a wide variety of research projects, including studies on a) porphyrinic materials; b) plant transcription factors; c) agricultural oligomers; d) polyoxometallate speciation; and e) protein phosphorylation. Matrix-assisted laser desorption ionization (MALDI) time-of-flight (TOF) mass spectrometry is the technique of choice for obtaining accurate molecular weights on very large molecules, with extremely high sensitivity. Use of a MALDI-TOF mass spectrometer has therefore become a standard technique, especially in studies involving biomolecules. This research will have a significant impact in a number of areas, especially materials science and biochemistry
