The set-up of PIPERADE will be used to purify the radioactive ion beam at the future SPIRAL2 facility of GANIL. The mass separation will be performed with a double Penning trap which will be built in a collaboration between the MPIK in Heidelberg, the CENBG in Bordeaux and the CSNSM in Orsay. The main requirements for this system are a high resolving power (105) for the separation of close masses and a high loading capacity (>107) due to the large ratio between the amount of the isobaric contaminants and the ions of interest. First results from simulations and test measurements, performed to find an efficient cleaning method, will be presented. In particular some Coulomb effects have been investigated and new excitation methods have been tested and simulated.
