Hello,
Outside reasonable distances (10 feet), the mass specs
will probably have no problem with the static field
from the NMR magnets. This is even more true since you
are considering shielded magnets.
However, the mass specs often have rapidly varying
magnetic fields when they are scanning. These sweep
fields from the mass specs can interfere with NMRs
for large distances (> 100 feet in some cases). This
interference would be greatly reduced by shielded
NMR magnets but it is an area to investigate before
locating mass specs and NMRs in the same general area.
