Universality of the ion guide technique allows the mass separation of isotopes of any element. However, this feature also means unselectivity in respect to chemical element number and results in severe isobaric background. Also the operation of the ion guide with the maximum yield increases the energy spread and the emittance of the ion beam. To overcome these problems, new means to cool, bunch and mass purify the ion beam will be developed. The weak radioactive ion beam will be cooled in a gas-filled radiofrequency quadrupole and further mass purified and bunched in a Penning-trap.
