Single crystal diffractometer

至少自20世纪70年代末以来，如果没有X射线单晶结构分析，现代合成/分子化学是不可能的。除了结构参数的分析外，它早已成为确定分子中原子间连接的最重要的方法。从这个角度来看，单晶X射线结构分析是任何化学研究所都不能缺少的常规分析方法。单晶X射线结构分析属于罗斯托克大学化学研究所的中央服务(ZD)，该中心由舒尔茨教授组织。ZD的一部分是单晶X射线衍射部，由PD亚历山大·维林格博士领导。应当指出的是，单晶X射线衍射系的职能是为整个罗斯托克大学提供服务，即它服务于化学领域(特别是无机化学和有机化学)以及所有其他学科(物理、材料科学等)的请求。通过此应用程序，我们请求更换2008年投入使用的设备(Kappa APEX II，Bruker AXS)。不幸的是，该设备的使用寿命即将结束，这表明，它在最近几年由于问题而非常频繁地停止工作，因为它非常容易受到故障和维修的影响，这有时导致在6个月的时间内无法测量单晶(！)，因为我们布鲁克公司的第二台衍射仪也因探测器缺陷而停止工作。这对科研工作造成了很大的损害，在理科、硕士和博士论文的执行中出现了许多问题。此外，许多维修费用很高，像我们这样的小研究所很难负担得起。替代方案应确保今后继续为罗斯托克大学的化学学科和邻近学科提供现代化的衍射仪设备。

Modern synthesis/molecule chemistry is no longer conceivable without single crystal structure analysis by means of X-ray diffraction, at least since the end of the 1970s. It has long since become the most important method for determining the linkage of atoms in a molecule, in addition to the analysis of structural parameters. From this point of view, single crystal X-ray structure analysis is a routine analytical method that no chemical institute should be without. The single crystal X-ray structure analysis belongs to the central services (ZD) at the Institute of Chemistry of the University of Rostock, which are organised by Prof. Dr. Schulz. Part of the ZD, is the department of single crystal X-ray diffraction, which is headed by PD Dr. Alexander Villinger. It should be pointed out that the Department of Single Crystal X-ray Diffraction functions as a service facility for the entire University of Rostock, i.e. it serves requests from the field of chemistry (especially inorganic and organic chemistry), but also from all other disciplines (physics, material sciences, etc.). With this application, we are requesting a replacement for a device (Kappa APEX II, Bruker AXS) that was put into operation in 2008. This device is unfortunately at the end of its service life, which is expressed, among other things, that it has stopped working extremely often in recent years due to problems, as it is extraordinarily susceptible to faults and repairs, which sometimes led to the fact that no measurement of single crystals was possible for a period of 6 months(!), as our second diffractometer from the Bruker company also stopped due to a defective detector. This led to a very strong impairment of the scientific work and many problems in the execution of BSc, MSc and PhD theses. In addition, the many repairs led to high costs, which a small institute like ours can hardly afford. The replacement should ensure that the chemically oriented sciences and also the neighbouring disciplines of the University of Rostock will continue to be provided with modern diffractometer equipment in the future.
