WebShimming a magnet for use in NMR is similar to many sports: mental attitude is a key to success. Shimming is often made more difficult than necessary by the operator™s belief that it is a fimagicfl process far too complex to understand. Successful shimming is a simple, but often very time-consum-ing, process. WebHere we cover the basics of lock and shim. The transcript can be found at: http://nmrlab.technion.ac.il/htms/demo.htm
Web3D Shimming – creates a daily base shim set (X, Y, and Z shims) to optimize resolution and reduce the amount of time spent on routine shimming (Z shims only). Quantification – ensures qNMR integrity so users have confidence in the spectrometer calibration The key ingredient to generating great NMR data
