Highly sensitive magnetochemical measurements of condensed phase samples are one of the most important measurement methods in bioinorganic chemistry, materials chemistry, catalysis, as well as in solid state physics and spintronics. Therefore, a large number of magnetic measurements are routinely carried out in the research fields of chemistry, biochemistry and physics at the Johannes Gutenberg University Mainz. In chemistry, current and technologically relevant phenomena in the fields of single molecule magnetism, spin crossover, (photo-) catalysis are investigated. In solid-state chemistry and physics, studies are carried out in the field of magnetic order in solid-state structures as well as data storage and data processing (spintronics). Since this often involves samples with very low magnetic moments, measurements with high sensitivity are required. At JGU Mainz, a SQUID magnetometer (superconducting quantum interference device) has been operated by AK Prof. Eva Rentschler for 15 years. Due to its age, this instrument is now massively susceptible to faults. In addition, the procurement of replacement components is becoming increasingly difficult and cost-intensive. In some cases, self-made solutions had to be developed. The instrument service for the instrument was already discontinued by the manufacturer in 2018. Accordingly, this application represents a replacement procurement for a highly modern, high-performance SQUID magnetometer, which will ensure productive magnetometric work at the Mainz site for the coming years. The application also takes into account the very high sample volume and the significantly increased need for measuring capacity due to new appointments at the site. Accordingly, the proposed device should be equipped with the necessary equipment to address current questions in ongoing and planned research projects and research associations.

冷凝相样品的高度敏感磁化学测量是生物促进化学，材料化学，催化以及固态物理学和旋转型的最重要的测量方法之一。因此，在约翰内斯·古腾堡大学的化学，生物化学和物理学的研究领域，通常在Mainz的化学，生物化学和物理学研究领域进行大量磁测量。在化学中，研究了单分子磁性，旋转跨界，（照片）催化的当前和技术相关现象。在固态化学和物理学中，在固态结构的磁顺序领域以及数据存储和数据处理（SpinTronics）中进行了研究。由于这通常涉及磁矩非常低的样品，因此需要具有高灵敏度的测量。在JGU Mainz，AK教授Eva Rentschler经营了15年。由于其年龄，该仪器现在非常容易受到断层的影响。此外，替换组件的采购变得越来越困难和成本密集。在某些情况下，必须开发自制的解决方案。该仪器的仪器服务已经由制造商在2018年停止。因此，该应用程序代表了对高度现代，高性能的鱿鱼磁力计的替代采购，这将确保未来几年的Mainz站点的生产力磁力计。该应用程序还考虑了由于现场新约会而导致的测量能力的很高样本量以及显着增加的需求。因此，所提出的设备应配备必要的设备，以解决正在进行和计划的研究项目和研究协会中的当前问题。
