The elucidation of molecular structures in the solid state by X-Ray diffraction is the gold standard for characterizing newly-synthesized compounds. Thus, this method belongs to the routine-equipment of chemical institutes since the 1980s. Also adjacent fields increasingly use these methods. At Saarland University, the powder- and single-crystal X-Ray diffraction instruments are operated and heavily used by the inorganic chemistry groups. Further, their use is provided also to all other chemical subdisciplines (organic and physical chemistry) as service, which is also the case for other institutes (pharmacy, material sciences). Herewith, we apply for the replacement for an aged single-crystal X-Ray diffractometer brought into service in 2004. It is approaching the end of its lifetime, as the supplier does not guarantee anymore spare parts and repairs since 1/2021. The instrument to be replaced is prone to breakdown for a couple of years now, which significantly slows scientific progress (mostly, yet not exclusively of the inorganic chemical institutes) and generates high financial expenditures. As such, it also binds all the time of the instrument’s responsibles. This replacement will allow the chemical sciences as well as adjacent disciplines at Saarland University to have access to an adequate and timely equipment also in the future.

通过X射线衍射对固态分子结构的解析是表征新合成化合物的金标准。因此，该方法属于80年代以来化工院校的常规设备。邻近的油田也越来越多地使用这些方法。在萨尔兰大学，粉末和单晶X射线衍射仪被无机化学组大量使用。此外，它们的使用也提供给所有其他化学分支学科（有机和物理化学）作为服务，这也是其他研究所（制药，材料科学）的情况。兹申请更换2004年投入使用的老化单晶X射线衍射仪。由于供应商自2021年1月起不再保证备件和维修，其使用寿命即将结束。要更换的仪器在几年内很容易出现故障，这大大减缓了科学进步（主要是，但不完全是无机化学研究所），并产生了高额的财政支出。因此，它也约束文书的所有责任人。这一更换将使化学科学以及萨尔兰大学的相邻学科在未来也能够获得足够和及时的设备。
