There are occasions where a conventional “sum” integration is spoiled by the unfortunately placed impurity peaks in the region that we would like to accurately integrate.
For conventional spectral analysis GSD peak picking and integration has a lot to offer, but for the very best results that qNMR usually demands “sum” integration is king. Dr John Gauvin (DSM, Holland) recently gave an excellent webinar presentation where he compared the errors and accuracy that can be expected when either “sum” or “peaks” (GSD) integration is used. QNMR is a common theme in my blogs, and it is always interesting and fun to speak with the growing number of like-minded colleagues.
