MRI: Acquisition of a MALDI/FT-ICR mass spectrometer for multidisciplinary research

鲍登学院化学系将获得一台配备外部基质辅助激光解吸/电离（MALDI）和电子电离（EI）源的傅里叶变换离子回旋共振（FT-ICR）质谱仪，该质谱仪来自主要研究仪器（MRI）项目。鲍登学院（Bowdoin College）、贝茨学院（Bates College）和南缅因大学（University of Southern Maine）的教职员工将可以使用该设备，这将加强在许多领域的研究，包括a)气相离子-分子反应的研究；B)生物、聚合物和有机金属合成靶标的鉴定；c)表征样本，包括来自海洋无脊椎动物的神经元，植物色素提取物，土壤样本和考古收集的油残留物。质谱（MS）是一种用于探测内部结构细节和获得大量有机、生物有机和有机金属分子的分子组成的技术。该仪器将作为教育学生和教师关于MALDI和FT-ICR质谱新技术的工具。此外，由于这种仪器技术非常适合分析各种样品，FT-ICR将催化神经科学、生态学、生物学、环境研究和考古学等学科的新研究方法和新研究活动。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Bowdoin College will acquire a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer equipped with external matrix-assisted laser desorption/ionization (MALDI) and electron ionization (EI) sources. Faculty at Bowdoin College, Bates College and the University of Southern Maine will have access to this equipment, which will enhance research in a number of areas including a) studies of gas-phase ion-molecule reactions; b) identification of biological, polymeric, and organometallic synthetic targets; and c) characterization of samples that include neurons from marine invertebrates, plant pigment extracts, soil samples, and oil residues from archaeological collections. 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. This instrument will serve as a vehicle to educate students and faculty about the new technologies of MALDI and FT-ICR mass spectrometry. In addition, because this instrumental technique is well suited for the analysis of a wide range of samples, the FT-ICR will catalyze new approaches to research and new research activities in disciplines such as neuroscience, ecology, biology, environmental studies and archaeology.
