Hochauflösendes Massenspektrometer

在无机化学研究所，将安装一台具有各种电离方法（ES I，HPLC-ESI，APCI，ASAP，LIDFI）的高分辨率质谱仪，以满足目前活跃的八个研究小组的各种分析要求。由于该研究所的研究重点在过去4-5年中显著扩大，迫切需要扩大分析设施，任命了5名新教师和2个初级研究小组，导致工作人员（博士生，博士后和长期研究人员）从约70人增加到120多人。目前，内部可用的质谱分析仅限于GC/MS，这与许多研究人员对温和电离方法（如电喷雾或场解吸）的要求不匹配。此外，这些具有单位质量分辨率的Singlequadrupole仪器不允许确定精确的质量和分配求和公式。安装在学院其他地方的其他质谱仪被各自的所有者完全占用，因此无法共享使用。因此，迫切需要扩大无机化学研究所的质谱设施，以满足越来越多的研究人员的分析需求，这些研究人员依赖于各种电离方法。

At the Institute for lnorganic Chemistry, a high-resolution mass spectrometer with a wide range of ionisation methods (ES I, HPLC-ESI, APCI, ASAP, LIDFI) is to be installed to satisfy the diverse analytical requirements of the eight research groups now active. An expansion of the analytical facilities is urgently needed as the research focus of the institute has significantly broadened within the last 4-5 years with the appointment of five new faculty members and two junior research groups, leading to a concomitant increase in staff members (doctoral students, postdocs, and permanent research staff) from about 70 to over 120. Currently, mass spectrometric analysis available in-house is limited to GC/MS, which does not match the requirements of many researchers for mild ionisation methods such as electrospray or field desorption. Furthermore, these Singlequadrupole instruments with unit mass resolution do not allow determination of exact masses and assignment of sum formulas. Other mass spectrometers installed elsewhere in the faculty are fully occupied by their respective owners and thus not available for shared use. Therefore, the expansion of the mass spectrometric facilities at the Institute for lnorganic Chemistry is urgently required to serve the analytical needs of a significantly increased number of researchers which rely on a diverse spectrum of ionisation methods.
