500 MHz NMR spectrometer

改进的，以研究为导向的核磁共振教育和化学与药学院高度活跃的研究工作组的结合导致了现有高场研究核磁共振光谱仪的严重超载。此外，300兆赫光谱仪已经使用了20多年，故障越来越多。由于整个学院的研究光谱仪数量较少，因此该光谱仪的终端故障是不可等待的。因此，购买一台新的500 MHz核磁共振光谱仪对于确保未来几年基于核磁共振或使用核磁共振的研究项目的可行性至关重要，同时满足对测量时间和教职员工特殊测量的需求。这次收购不仅将大大增加可用的测量时间，减轻旧的300 MHz光谱仪可能出现故障的影响，而且由于新一代控制台改进的动态和绝对灵敏度，还可以检测较低浓度的物质。特别重要的是使用高度敏感的Prodigy冷冻样品头，因为沃尔夫教授的小组正在集中研究空气敏感的、难溶的含磷化合物，其中磷不参与自旋-自旋与质子的相互作用，这一事实是必要的。

The combination of improved, research-oriented NMR education and highly research-active working groups at the Faculty of Chemistry and Pharmacy has led to a severe overload of the existing high-field research NMR spectrometers. Moreover, the 300 MHz spectrometer, which is over 20 years old, is increasingly suffering from failures. Due to the small number of research spectrometers for the entire faculty, a termial failure of this spectrometer cannot be waited for. Therefore, the acquisition of a new 500 MHz NMR spectrometer is essential to ensure the feasibility of NMR-based or NMR-using research projects in the coming years and, at the same time, to meet the increased demand for measurement time and special measurements of the faculty. This acquisition will allow not only a significant increase in the available measurement time and mitigation of the effects of a possible failure of the old 300 MHz spectrometer, but also the detection of lower concentrations of substances due to the improved dynamic and absolute sensitivity of the new generation console. Of particular importance is the use of a highly sensitive Prodigy cryosample head, necessitated by the fact that Professor Wolf's group is intensively working with air sensitive, poorly soluble phosphorus containing compounds, in which phosphorus is not involved in spin-spin interactions with protons.
