An overview is given on recent
measurements with extreme precision on single or few
cooled ions stored in Penning traps. On the one hand, mass measurements provide
crucial information for
atomic, nuclear and neutrino physics as well as
for testing fundamental symmetries. On the other and,
g-factor measurements of the bound
electron in highly-charged hydrogen-like ions allow for the
determination of
fundamental constants and for constraining Quantum Electrodynamics.
For example,
the most stringent test of CPT symmetry in the baryonic sector could be performed by
mass comparison of the antiproton with H
- and the knowledge of the electron atomic mass
could be improved by a factor of 13.
