WebbThis is the auto-sampler. The NMR in the image is identical to ours, except we have the Ascend 400 MHz. We run Bruker Topspin. The ‘IconNMR Automation’ is a program you could use within Bruker Topspin to set up a queue. Allows samples to run automatically. WebbSolving Problems with NMR Spectroscopy, Second Edition, is a fully updated and revised version of the best-selling book. This new edition still clearly presents the basic principles and applications of NMR spectroscopy with only as much math as is necessary. It shows how to solve chemical structures with NMR by giving many new, clear …

WebbWith natural products we normally struggle to get more than 1 mg, and when running in a 5mm tube, you mainly see the solvent or have a poor signal to noise ratio. While visiting labs overseas, I noticed they were purifying <1mg and yet were able to do full characterisation using a 1.7 mm tube on a 500MHz without a cryoprobe. Webb31 aug. 2024 · Many similar technical challenges, and often regulatory burdens, are shared across these fields, yet there is often little cross-talk between the various NMR practitioners in each of these focused areas. Greater sharing of experience and expertise amongst practitioners of applied NMR would be of benefit to all.
