After nine years in development, a superconducting magnet, weighing 16 tons and standing 21 feet high, was delivered to PNNL in March. It is part of a 900 megahertz wide-bore nuclear magnetic resonance spectrometer. The NMR is a powerful scientific instrument that will enable scientists to make new discoveries in chemical, physical, biological and life sciences. When fully operational, it will be the world's largest, highest- performing NMR, enabling researchers to investigate larger and more complex molecules at resolutions never before available.
