500 MHz NMR spectrometer

化学和药学院改进的、以研究为导向的核磁共振教育和高度研究活跃的工作组相结合，导致现有的高场研究核磁共振光谱仪严重超载。此外，已有20多年历史的300 MHz光谱仪也越来越多地出现故障。由于整个教职员工的研究光谱仪数量很少，这台光谱仪的终极故障迫不及待。因此，购置一台新的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，同时满足教师对测量时间和特殊测量的日益增长的需求是至关重要的。这一收购不仅将显著增加可用测量时间并缓解旧300 MHz光谱仪可能发生故障的影响，而且由于新一代控制台改进了动态和绝对灵敏度，还将检测到更低浓度的物质。尤其重要的是使用高度敏感的Prodigy冷冻采样头，这是因为Wolf教授的团队正在密集地研究对空气敏感、难于溶解的含磷化合物，其中磷不参与与质子的自旋-自旋相互作用。

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.
