What is a good way to calibrate PFG? How do you prepare the most suitable sample for the calibration? |
Brian Antalek has explained it nicely in his paper "Using pulsed gradient spin echo NMR for chemical mixture analysis: How to obtain optimum results" There is additional information in "Improving the accuracy of pulsed field gradient NMR diffusion experiments: Correction for gradient non-uniformity", by Conell et al. |
