The Penning trap ion cooler REXTRAP has been upgraded with a mass-separation technique to clean REX beams from isobaric impurities. The system was lately demonstrated to work with stable beams. It showed a maximum resolution of about 30 Hz in the case of 40K/40Ca, corresponding to a mass resolving power of M/dM ~40000, enabling to resolve many radioactive isobars from stable and radioactive contaminations. The technique will be briefly introduced and the possibilities and limitations will be dicussed.
