JEOL NMR systems have had all FDA 21 CFR Part 11 support functions available in the standard Delta software since version 4.3 was released in 2004. All newer versions of the software have maintained and added to this functionality.

"pure shift" is  method for homo nuclear broad band decoupling. Sensitivity would be reduced, but spectra of only (pure) chemical shifts can be obtained by eliminating j coupling.
