In Project B10, Dynamic Nuclear Polarization (DNP) techniques are employed for Nuclear Magnetic Resonance (NMR) signal enhancement. DNP techniques enable overcoming the inherently low nuclear spin polarization and thus allow new applications of this important method. In this project, DNP hyperpolarization techniques are combined with NMR relaxometry as well as with high and medium field (benchtop) NMR. Both the electron-nuclear spin coupling itself and its application in process engineering are studied. The aim is to boost the sensitivity of NMR experiments manifold so that quantitative measurements of components at low concentrations or in small geometries such as microfluidic devices become possible.

在项目B10中，动态核极化（DNP）技术用于核磁共振（NMR）信号增强。 DNP技术可以克服固有的低核自旋极化，从而允许这种重要方法的新应用。在该项目中，DNP超极化技术与NMR弛豫计以及高和中场（台式）NMR结合使用。研究了电子核型自旋耦合本身及其在工艺工程中的应用。目的是提高NMR实验歧管的敏感性，以便对低浓度或小几何形状（例如微流体设备）的组件进行定量测量。
