Magic Angle Spinning NMR Experiments on Radioactive Samples with a Microcoil Spinner
EMSL Project ID
19194
Abstract
The solid-state NMR group at the CEA of Saclay has designed and patented a novel micro-coil spinner to meet the stringent safety and sensitivity challenges of magic-angle-spinning (MAS) experiments on radioactive solids. While extensive testing with non-radioactive samples has been performed in our laboratory in France, the NMR facility in the PNNL Radiochemical Processing Laboratory is currently the only location in the world where the next steps in the development and evaluation of the micro-coil spinner can be performed. A future goal is to use the micro-coil spinner to investigate model mineral phases under consideration by the French government as immobilization hosts for high-level radioactive waste.
