Penning traps are widely used as storage devices for charged particles. Based on these ion traps Fourier Transform Ion Cyclotron Resonance mass spectrometry (FT-ICR MS) has become a standard method for for both analytical and precision measurements. A broad-band FT-ICR detection system for monitoring the ion concentration at the KATRIN beamline has been developed and characterized at the Max-Planck-Institute for Nuclear Physics in Heidelberg. In addition, the on-line tests have been extended to fundamental studies on the ion motion, in particular by applying Ramsey excitation. In this contribution recent results of both studies, the off-line KATRIN tests and the Ramsey method, will be presented.
