One of the main scientific goals of the SHIPTRAP experiment at GSI is mass spectrometry on heavy transuranium nuclides produced at the velocity filter SHIP. Nowadays the destructive time-of-flight-ICR (Ion Cyclotron Resonance) method is exclusively used for the mass determination of radionuclides in a Penning trap. Since the production rate for the nuclides of interest at SHIP is extremely low, the non-destructive and highly-sensitive Fourier Transform FT-ICR technique will be employed. It enables measurements even on single ions. First experimental tests and specification measurements with the cryogenic trap system will be performed off-line using stable cesium ions. For the future commissioning of the setup and the comparison of both detection schemes a detector tandem consisting of a microchannel plate and a channeltron will be used. In this contribution the detection techniques, the experimental goals as well as first results will be presented
